Limit to array size?

[JimmyFo]

Hi, I am trying to create an array of structs to hold some basic information. I'm looking at something like this:

struct frame
{
int file1[153];
string file2[153];
int file3[153];
float file4[153];
};

frame newArray[558];

I can build this in VS 2005, but when I try to run it, I get a memory access error. I started with an entirely blank project, and have only on .h and one .cpp file, less than 100 lines at this point.

If I take the newArray[] size down to around 250, it's ok - why is this?

Thanks,
James

Your array it too big for your stack. Allocate it on the heap instead:

frame* newArray = new frame[ 558 ];

Or even better, just use a vector instead of an array:

vector<frame> newArray;

Thank you, I will try both!
