how large can be the allocation in stack?

[kai2005]

the code like this:

int main()
{
int intArray[10000][10000]; //I got no problem,
//but I got problem in run time
//now I think the space demand
//is too large.
//now the question is, how can I know
//how large maximum will be stack?
// some code more ...
return 0;
}

Use the project settings to adjust the appropriate linker parameter.

Though you should look to use dynamic memory allocation for such large data structures.

Salem,

thanks for your answer.

I have not used VC, but just compile my code with gcc. How can I deal with this problem?

I have just made a test, till 721*722*4 Byte is still ok. above this will get problem. And 721*721*4 = 1.98MB That mean, the default max stack size for gcc is 2MB.

I don't know how can I make some changement by setting of stack size.

You should have said so, since you posted on a compiler specific forum.
Which version of gcc (there are many different ports for windows).
Cygwin / MinGW / dev-c++ / DJGPP ?

You could always do
[tt]static int largeArray[1000][1000];[/tt]
