Python beginner, strange output problem
|
<p>I'm having a weird problem with the following piece of code.</p>
<pre><code>from math import sqrt
def Permute(array):
result1 = []
result2 = []
if len(array) <= 1:
return array
for subarray in Permute(array[1:]):
for i in range(len(array)):
temp1 = subarray[:i]+array[0]+subarray[i:]
temp2 = [0]
for num in range(len(array)-1):
temp2[0] += (sqrt(pow((temp1[num+1][1][0]-temp1[num][1][0]),2) + pow((temp1[num+1][1][1]-temp1[num][1][1]),2)))
result1.append(temp1+temp2)
return result1
a = [['A',[50,1]]]
b = [['B',[1,1]]]
c = [['C',[100,1]]]
array = [a,b,c]
result1 = Permute(array)
for i in range(len(result1)):
print (result1[i])
print (len(result1))
</code></pre>
<p>What it does is find all the permutations of the points abc and then returns them along with the sum of the distances between each ordered point. It does this; however, it also seems to report a strange additional value, 99. I figure that the 99 is coming from the computation of the distance between point a and c but I don't understand why it is appearing in the final output as it does.</p>

Developing high load sites with java
|
<p>Is there any web sites written with java that serve millions of users?</p>
<p>From what I've seen, popular web sites generally using php, asp.net. Is this because of servlet technology or development costs?</p>
<p>===============After close===========</p>
<p>I am currently developing web applications using JSF ,Spring MVC +JQUERY . In the past ,I had developed web applications using asp.net . Applications we developed are seems to me and Workmates(they have mostly php experince) slow .So we want to know ,</p>
<p>Are we missing something or Servlet technology come with cons.</p>

Question on Event name of javascript

<p>I want to ask a question about the javascript event. I have a <code><input type="text"></code> box and I have applied the autocomplete function on that box.</p>
<p>I know that when the user types the char like "sta" in the box and the javascript will call the <code>keypress</code> event, which also calls the autocomplete function. </p>
<p>However, I want to know what event of the javascript will be called what I use the mouse to click/click the keybroad "enter" to the wanted item from the autocomplete list. Thank you.</p>

Use drawable with ShaderFactory in LayerDrawable

<p>I am having trouble using a Drawable with ShaderFactory in a LayerDrawable. It is showing all black instead of to the two layers (none of which should be all black). It worked when I used a static Shader using drawable.getPaint().setShader(), but not now with ShaderFactory. </p>
<pre><code>ShapeDrawable.ShaderFactory sf = new ShapeDrawable.ShaderFactory() {
@Override
public Shader resize(int width, int height) {
Log.d("shader", width+"x"+height);

new float[] { 0.0f, 0.04f, 0.97f, 1.0f }, Shader.TileMode.CLAMP);
return gradient;

JavaScript variables scope and underscore.js
|
<p>I have a function, with this inside it:</p>
<pre><code>var fobj = function(){};
var my_obj = fobj.extend({
test: function(){
this.year = 1999;
my_fmagic.doMagic([
{
field: 'year',
type: 'function',
value: function(data_from_doMagic){
console.log(data_from_doMagic, this.year);
return data_from_doMagic == this.year;
}
}
]);
}
});
</code></pre>
<p>Then, the <code>doMagic</code> function:</p>
<pre><code>var fmagic = function(){};
var my_fmagic = fmagic.extend({
doMagic: function( rules ) {
var data_from_doMagic = 1999;
_.each(rules, function(rule) {
switch(rule.type) {
case "function":
var f = _.wrap(rule.value, function(func){
return func( data_from_doMagic );
});
f();
break;
}
});
}
});
</code></pre>
<p>The idea is: pass an array of "rules" to <code>doMagic</code> and let it do the rest.</p>
<p>Expected result: <code>test()</code> should return <code>true</code> (well, in this example it won't return anything, obviously, because there's no return, but the <code>value</code> field of the rule should be <code>true</code>.) </p>
<p>Problem: Instead the result being <code>true</code> it's <code>false</code>, because the function <code>f()</code> in <code>doMagic</code> doesn't know what the variable <code>year</code> is, and so it compares "1999" with "undefined".</p>
<p>As you can see I know where the problem is, but I can't think about any solution.</p>
<p>Ideas?</p>
<p>Regards</p>

Lowering script memory usage in a "big" file creation
|
<p>it looks like I'm facing a typical memory outage problem when using a PHP script.</p>
<p>The script, originally developed by another person, serves as an XML sitemap creator, and on large websites uses quite a lot of memory.</p>
<p>I thought that the problem was related due to an algorithm holding data in memory until the job was done, but digging into the code I have discovered that the script works in this way:</p>
<ul>
<li>open file in output (will contain XML sitemap entries)</li>
<li>in the loop:
---- for each entry to be added in sitemap, do fwrite</li>
<li>close file</li>
<li>end</li>
</ul>
<p>Although there are no huge arrays or variables being kept in memory, this technique uses a lot of memory.</p>
<p>I thought that maybe PHP was buffering under the hood the fwrites and "flushing" data at the end of the script, so I have modified the code to close and open the file every Nth record, but the memory usage is still the same.... I'm debugging the script on my computer and watching memory usage: while script execution runs, memory allocation grows.</p>
<p>Is there a particular technique to instruct PHP to free unsed memory, to force flushing buffers if any?</p>
<p>Thanks</p>

What does the MediaPlayer message "internal/external state mismatch corrected" mean?
|
<p>I've been doing some pretty complex things with the MediaPlayer. Unlike <a href="http://stackoverflow.com/questions/7399286/android-media-player-internal-external-state-mismatch">Android Media Player internal external state mismatch</a>, I'm only working with audio, not video. The MediaPlayer class is notoriously fragile and unintuitive, so it's difficult to work around its quirks. I've been doing the best I can, but still run into difficult-to-diagnose bugs.</p>
<p>In this case, I occasionally see the error message "internal/external state mismatch corrected". I have no idea why. I'm running multiple MediaPlayers simultaneously, using MediaRecorder and then playing it in a MediaPlayer, stopping and starting and resetting and seeking... at least some of the time it seems to occur after start().</p>
<p>Is this a bug in Android, or am I doing something wrong? Can anyone tell me what this error message represents, and if there's something I should be doing differently or if I can safely ignore it?</p>

How to let java to substitute chars in string and make it executable
|
<p>I haven't found any information if it's even possible. I want to use method or some other way to return string and put it into for loop so that when loop executes it can put loop parameters into returned string and compose new string. As you probably guess I want to insert keyStr into hashmap but with substitutions as is done in dynamicKeyStr. dynamicKeyStr solution is great but it's structure may change over time that's why I cannot write it statically.</p>
<p>Sometimes it's:</p>
<pre><code>dynamicKeyStr = array[i][1]+"-"+array[i][3]+"-"+array[i][8];
</code></pre>
<p>Another time it's:</p>
<pre><code>dynamicKeyStr = array[i][13]+"-"+array[i][5];
</code></pre>
<p>and so on.</p>
<pre><code>public void dynamicForLoop() {
for (int i = 0; i < array.length; i++) {
String dynamicKeyStr = array[i][1]+"-"+array[i][3]+"-"+array[i][8];
//String KeyStr = "array[i][1]+\"-\"+array[i][3]+\"-\"+array[i][8]";
hashSet.add(dynamicKeyStr);

How to start and monitor an external command line process with java under windows XP
|
<p>I have a java question about launching and monitoring external processes under Windows XP.</p>
<p>I have written a coommand-line simulation program with C++ and mingw which takes an XML file as input file. I am now writing a pre-processor for that program (I call it "Launcher"). </p>
<p>Launcher allows user to edit parameters and save to an XML file, it also provides ability to start simulation process with an input file and kill the simulation process when it's still running. In order to do this, it must be able to monitor the launched command-line simulation process.</p>
<p>In Launcher, I created a new thread and I used <code>ProcessBuilder</code> or <code>Runtim.getRuntime()</code> method in its <code>run()</code> function to start simulation process. The command used to construct ProcessBuilder to start external simulation program was as follows:</p>
<pre><code>cmd.exe /c start <simulation program> -i <input file>
</code></pre>
<p>The simulation process did start as I expected with above command and a command window appears.However, the thread which contains this Process object ends immediately. Therefore, I couldn't track the process and terminate it from Launcher program.</p>
<p>I modified the command to following:</p>
<pre><code>cmd.exe /c start /wait <simulation program> -i <input file>
</code></pre>
<p>The thread used to start this process didn't end until the command-line window running the simulation process ended.
However, when I tried to interrupt this thread, the thread did end but the external simulation process didn't. Therefore, I still can't kill that process from my java program.</p>
<p>I have studied this problem for two days, most materials I found are focusing on how to start an external process but not focusing on monitoring it after it started. I hope I can find a simple and elegant way to start an external command-line process with Java under XP while I still can monitor and terminate that command-line process through the Java program which starts it.</p>

Does the API provide scroll buttons for ListView
|
<p>I have a client who wants a conventional scrollbar for ListViews in their application. The reason why is because this application will be used exclusively with their devices which happen to feature resistive screens. The screens don't track gestures very well without a stylus and a stylus will not always be available to the user. Hence the conventional scrollbar as a fallback UI control. A fast scroll thumb will not be a useful solution to this problem.</p>
<p>What I have found in the API that is of some use are xml attributes which allow me to approximate the behaviour of the track and thumb such as:</p>
<pre><code>android:scrollbarAlwaysDrawVerticalTrack="true"
android:scrollbarStyle="insideInset"
android:fadeScrollbars="false"
</code></pre>
<p>But I haven't found anything in the API that would take care of including scroll buttons at the top and bottom of the track. </p>
<p>Am I correct in concluding that the API does not provide this functionality?
If so, my only option would be to use a couple of buttons that change the list position. This is a doable solution of course but I wanted to make sure that I wasn't reinventing yet another wheel.</p>
<p>I have to support as far back as 2.2.</p>
<p>Scrollbar Example:</p>

Determine if empty $_POST submitted
|
<p>I have a form containing tabular data, with each row having a checkbox with the same name so that it gets passed via POST as an array to a PHP page. Everything work fine, but I have an issue relating to when none of the items on the page are selected - this is a special case that I need to handle in a specific way, but I am trying to figure out how to determine the best way to tell when this condition occurs, as when it does the <code>$_POST</code> array is completely empty.</p>
<p>Any strategies to help in determining when an empty set of data has been POSTed to a page in PHP?</p>

Solving engine for TicTacToe
|
<p>I'm a junior programmer and I know the basics of pascal and c++. I made a Tic Tac Toe game with Player-Computer and the game is all finished.</p>
<p>The computer generates a random place where the Os go on the table and that's not good.</p>
<p>I thought that i should multiple procedures that check every winning position and the computer should else try to block the player's Xs or to make a winning position, BUT this would have been lots of time lost cause all of the if's.</p>
<p>Then I thought of a simpler version with some kind of ifs but it would still have been taking lots of time to do.</p>
<p>Then i thought deeper: What about a find-four game? How in the earth someone would manage to check every space available and how it would've been possible that someone could make a function that checks absolutely any winning or progress of player/computer position, Oh and wait, that's not ALL, what if the player is doing some tricks so he blocks the computer? How would the computer know that?!? For sure, that would take ages to program. And I am not talking about something that seems more impossible: Chess.</p>
<p>So here I am, asking myself that there SHOULD be a way more simpler way the computer should search and solve some problems than tons of ifs. </p>
<p>In this case, if any of you know any way of solving this, how can i manage to make the simplest procedure to block and beat the player in a TicTacToe game?</p>
<p>If someone wants to check my code or use it: <a href="http://pastebin.com/jhyUn7d1" rel="nofollow">http://pastebin.com/jhyUn7d1</a></p>

PHP if() evaluation problem needs a rewrite
|
<p>I noticed this weird evaluation yesterday after searching for a few hours in my code for an error. i am passing scores into php, sometimes the score=0 which causes an issue.</p>
<p>send php ?blah=blah&score=0</p>
<pre><code>if(!empty($_REQUEST['score']){
//do database update stuff
}else{
// show entire webpage
}
</code></pre>
<p>It works great unless the score=0 the if() will evaluate to false and return the entire webpage to my ajax handler and error. I have temporarily changed !empty to isset but this will cause problems in the future because isset evaluates to true even if the score key is in the url string without a value.<br>
ex: (?blah=blah&score=&something=else)</p>
<p>my question is: what is the best way to recode this to work correctly now and in the future?</p>
<p>edit: there are a few working answers here, i appreciate everyones time. it was difficult to choose an answer</p>

Why do we need `class` in C++?
|
<p>Using <code>struct</code> we can achieve all the functionalities of a <code>class</code>:</p>
<ul>
<li>constructors, destructors </li>
<li>member functions, static functions.</li>
<li>overloaded functions, virtual functions </li>
<li>public / private / protected access specifiers.</li>
<li>operators</li>
</ul>
<p>The only difference are the default access rights: private for class, public for struct.<br>
Why do we need a Class then ?</p>

Javascript - why this loop ? instance->(prototype property->constructor property->function object->constructor property)
|
<p>I am unable to understand this loop behavior of the javascript.</p>
<p>Can someone tell me why was it designed in this way?
Is there any real use case of this behavior?</p>
<p>why this loop? {
Newly created instance inherits properties from the prototype property of the constructor function object.
prototype property of the constructor function is an object that keeps constructor property.
constructor property is equal to the constructor function object.
Again constructor function object keeps prototype property.
}</p>
<p>instance1---inhertis(keeps)-->Prototype property of func()-->keep constructor property-->function object func-->keep prototype property.</p>
<pre><code>var func = function(){};
var construct = func.prototype.constructor;
console.log(construct === func); //true
var instance1 = new func();
</code></pre>
<p>Updated: Even if in between i assigned something else, instanceof always returns true.</p>
<pre><code>var func1 = function(){};
func1.prototype.constructor = 1;
var instance1 = new func1();
console.log(instance1 instanceof func1); //true
var func2 = function(){};
func2.prototype.constructor = 0;
var instance2 = new func2();
console.log(instance2 instanceof func2); //true
</code></pre>

Setting a boolean attribute with jquery

<p>I understand that jquery will allow you to modify attributes with the .attr() method. There are basically two methods:</p>
<pre><code>$('#element').attr('attribute', 'value') // sets the attribute
var attribute = $('#element').attr('attribute') // gets the attribute
</code></pre>
<p>My question is, how do you set a boolean attribute such as 'checked' on a checkbox or 'multiple' on a select tag?</p>
<p>I've tried doing the following without success:</p>
<pre><code>$('#element').attr('attribute', true)
$('#element').attr('attribute', '')

asp.net Domain / Subdomain Authentication not working correctly
|
<p>I have a w2k3 server which hosts 2 sites under iis, such that I have Mysite.com and foo.mysite.com</p>
<p>I am trying to use forms authentication and single sign on.</p>
<p>Both sites have the same machine key, and the same domain prefixed with a . in the web.configs.</p>
<p>The 2 issues I have are;</p>
<p>1) If I go to <a href="http://www.mysite.com/login.aspx" rel="nofollow">http://www.mysite.com/login.aspx</a>, and login, then navigate to the subdomain it redirects me back to the login page. </p>
<p>But if I go to <a href="http://mysite.com/login.aspx" rel="nofollow">http://mysite.com/login.aspx</a> and login, then navigate to the subdomain it works. so why is it seeing www.mysite.com and mysite.com as seperate domains and thus invalidating my authentication?</p>
<p>It is my understanding that adding domain=".mysite.com" would work for all sub sites under the domain.</p>
<p>2) If I change the subdomain login url to be mysite.com not www.mysite.com and hit the subdomain first, it redirects to the login form fine, but when I log in it does not redirect to the subdomain, rather it looks for the subdomain page on the main site. i.e. Browse to foo.mysite.com/bar.aspx, it redirects to the login page, and when logged in it now tries to show mysite.com/bar.aspx not the page I first requested.</p>
<p>Any help explaining and resolving these issues is most welcome!</p>
<p>Thanks</p>
<p>As an update to this. I found a workround to the redirect issue elsewhere on this site. Dont know why it doesnt work as I'd expect, but I can now cross that one off.</p>
<p>Secondly (on my test system anyway) programatically specifying the domain works with www. whereas using domain="" in teh config file does not.</p>

<p>But it doesn't seem to work. It works fine if I don't have the fadeOut before and just have it load. But is there a way to make it first fadeOut and then having it fadeIn slowly :)</p>
<p>Thanks</p>

Including If In Arrays Formed Using For
|
<p>In Python I have this statement:</p>
<pre><code>blog_ids = [c.blog_id for c in connections]
</code></pre>
<p>Which basically tells Python to create an array of all the blog IDs in the connections. Unfortunately, if the <code>connections</code> object has some <code>None</code> types, <code>c.blog_id</code> would cause an exception. Is there any syntax to solve this problem? I tried this but it doesn't work:</p>
<pre><code>blog_ids = [c.blog_id for c not None in connections]

How to show/hide DOM element with jQuery?
|
<p>There are button (id= "hide_message_button") and message(id="message"). The click on the button should hide/show the message. The source code:</p>
<pre><code>$('#hide_message_button').click(function(){
var bool = $('#message').css('visibility','hidden').is(':hidden');
if(bool){
$('#message').show();
$(this).val('Hide');
}
else {
$('#message').hide();
$(this).val('Show');
}
});
</code></pre>
<p>I have a bug: the message is hidden with first click on the button and didn't shown again (but button's value is changed to 'Show'). What's wrong? Thanks.</p>

ExpandoObject (dynamics) my greatest friend or my new greatest foe?
|
<p>Yes I know that it shouldn't be abused and that C# is primariy used as a static language. But seriously folks if you could just dirty up some code, in the python style, or create some dynamic do hicky, would you?</p>
<p>My mind is working overtime on this having spent a while loving the dynamics of python, is c# going over to the dark side through the back door?</p>
<p>Is the argument for static typing a dead one with this obvious addition?</p>
<p>Is the argument for less Unit testing a bit silly when we are all grown ups?</p>
<p>Or has the addition of dynamics ruined a strongly static typed and well designed language?</p>

Load Users into jQuery during onLoad of a page for a Live Search
|
<p>All,
I've got the following code to which is basically a function that loads some search terms in it when the DOM is loading:</p>
<pre><code>window.myAutocompleteFunction = function(){
return ['Test Saying','sit amet consectetur adipiscing','elit Nulla et justo'];
};
</code></pre>
<p>This works fine for my live search and updates correctly. I'm trying to populate these values based on some information from my database though. I tried to update my code to use a .get function to populate my return values and I tried to make it look like this:</p>
<pre><code>window.myAutocompleteFunction = function(){
$.get('http://localhost/website/load_users.php', function(data) {
alert(data);
return [data];
});
};
</code></pre>
<p>It tries to load the users and in my alert it is the same as when it's manually typed in but for some reason when I do the search it doesn't work. Any idea how to get the same results from my file and have the search work the same?</p>
<p><strong>EDIT:</strong> The only thing in my load_users.php file right now is the following:</p>
<pre>
'Test Saying','sit amet consectetur adipiscing','elit Nulla et justo'
</pre>
<p>I'm going to try and populate that with database values but just trying to get this to work for now.</p>
<p><strong>Another Edit:</strong> I also tried to make my code like the following just to see if it work work:</p>
<pre><code>window.myAutocompleteFunction = function(){
jQuery.get('http://localhost/okyne/load_users.php', function(data) {
alert(data);
return ['Test Saying','sit amet consectetur adipiscing','elit Nulla et justo'];
});
};
</code></pre>
<p>This doesn't work either so I'm not sure why it wouldn't work and the only thing that works for me so far is the first code snippet that I provided.</p>
<p>Any help you can provide is greatly appreciated!</p>

C# - Truncating after a position
|
<p>I have a double typed variable. This variable stores information that is part of a more complex formula. Importantly, this variable can only include information up to the tenths location, or one decimal position (i.e. 10.1, 100.2, etc). However, when determining this value, it must be calculated such that anything past the tenths location is truncated, not rounded. For instance:</p>
<p>if the value equals 10.44, The variable value should be 10.4.
if the value equals 10.45, The variable value should also be set to 10.4</p>
<p>How do I truncate values in C# with respect to a decimal place?</p>

Using instance variables as named format substitutions
|
<p>I am writing a Python program that generates a C++ program. There are a whole bunch of instances of code like this:</p>
<pre><code>class TestBlock(object):
def __init__(self, mod, name, casetype, generator):
self.mod = mod
self.name = name
self.casetype = casetype
self.generator = generator
def fullname(self):
return "{mod}.{name}".format(**self.__dict__)
def write_cases(self, outf):
outf.write("const {casetype} {mod}_{name}[] = {{\n"
.format(**self.__dict__))
for case in self.generator():
outf.write(" { " + case + " },\n")
outf.write("};\n\n")
</code></pre>
<p>The <code>"text {subst}".format(**self.__dict__)</code> construction is the only way I have found to make the instance variables of <code>self</code> available as named substitutions, and it's ugly and I do not like it. I would like to be able to write <code>"text {subst}".format(self)</code>; is this possible, and if so, how? I'm aware that <code>"text {0.subst}".format(self)</code> will work out of the box and <code>"text {subst}".format(**self)</code> can be made to work with a few special methods, but both of those still have extra gunk.</p>

How do I use a default setting from Root.plist?
|
<p>I have set up a default setting for my app using Root.plist, giving this a Boolean DefaultValue of YES (ticked checkbox).You can see a screengrab at <a href="http://www.infin8design.com/clients/stack/plist.png" rel="nofollow">http://www.infin8design.com/clients/stack/plist.png</a></p>
<p>However, when my app is first launched, the YES value is not picked up, and the setting is read as a NO (or 0). The user has to manually go into the settings app, turn the toggleswitch off, then turn it back on again for this setting to hold a YES(1) value.</p>
<p>I'm logging the value with appDidFinishLaunching like this.</p>
<pre><code>- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
NSLog(@"%d",[defaults boolForKey:@"include_phrases"]);
</code></pre>
<p>SO... my question is... How do I pick up this initial default setting without the user having to set it manually?</p>

Form buttons over-writing timeout events in javascript
|
<p>I'm developing a javascript based application and have continued to run into an issue that seems like a producer/consumer problem (it happens in both IE and firefox).</p>
<p>:Program Description:</p>
<p>There are two divs (A and B) in the page. A function is scheduled with timeouts to flip between the two divs every N seconds.</p>
<p>divs B has a form in it with buttons. the buttons have an on click call back set to them - the call back resets (refreshes) the form.</p>
<p>:Implementation Bug/Problem:</p>
<p>When div B displays and a user clicks on the buttons multiple times, the function (scheduled by a timeout) to flip the two divs never seems to execute. If it does execute, the display content is shown so quickly, it's as if the timeout was never called.</p>
<p>I've tried using a globally scoped state variable to control when button presses should be shut off, but that does not seem to work. Any advice or recommendations is welcome! Thanks!</p>
<p>Example</p>
<p>Imagine a 2 second window between each, the following diagram explains how it works with no onclick mouse events:</p>
<pre><code>seconds 0 2 4 6
+----+----+----+
divs A B A B
</code></pre>
<p>NOTE: the top row are the 2 second intervals, the bottom row are the div flip events</p>
<p>with mouse on click events it should do something like this (A is scheduled to happen exactly at 4 seconds):</p>
<pre><code>seconds 0 2 4 6
+----+----+----+
divs A BBBBBA B
</code></pre>
<p>what it currently does:</p>
<pre><code> seconds 0 2 4 6....
+----+----+----+....
divs A BBBBBBBBBBB....
</code></pre>
<p>the scheduled A event never happens.</p>

what's the size of hex value of some memory address converted to int or other type?
|
<p>For example:</p>
<pre><code>int* x = new int;
int y = reinterpret_cast<int>(x);
</code></pre>
<p><code>y</code> now holds the integer value of the memory address of variable <code>x</code>.
Variable <code>y</code> is of size <code>int</code>. Will that <code>int</code> size always be large enough to store the converted memory address of ANY TYPE being converted to <code>int</code>?</p>
<p><strong>EDIT:</strong>
Or is safer to use <code>long int</code> to avoid a possible loss of data?</p>
<p><strong>EDIT 2</strong>: Sorry people, to make this question more understandable the thing I want to find out here is the size of returned HEX value as a number, not size of int nor size of pointer to int but plain hex value. I need to get that value in in human-readable notation. That's why I'm using <code>reinterpret_cast</code> to convert that memory HEX value to DEC value. But to store the value safely I also need to fing out into what kind of variable to it: int, long - what type is big enough?</p>

int pnp[2][105],fin[2][105];
int time[105],n,m,dummy,prod = 0;
int const maxvv = 2000000;
int d[maxvv];
return 0;
}
</code></pre>
<p>I get a stackoverflow at <code>int d[maxvv]</code>. However, if I shift to the global scope</p>
<pre><code>#include<iostream>
#include<cstdio>
using namespace std;
int const maxvv = 2000000;
int d[maxvv];
int main(){
int pnp[2][105],fin[2][105];
int time[105],n,m,dummy,prod = 0;
return 0;
}
</code></pre>
<p>I do not get this error. Can anybody tell me what is the difference. Using vs 2008 with c++ on windows 7</p>
