I have a C++ object in some part of my code like this: 

class Object

{
public : 
float a, b, c;
}

When I create a 2 dimensional array like this, it works fine : 

Object myArray [500][500];

When I make it like this, I get segmentation fault : 

Object myArray [1000][1000];

What causes that segmentation fault, how can I get rid of it? Thanks.

To create a huge array, you need to make it global. Local variables have a size limit. Another solution is to allocate the array dynamically.

Stack has a limited size, usually 1 to 10 MB on a modern machine. You array takes at least 16 MB.

The best case for this would be to allocate the array on the heap.

Most likely you have exceeded the stack size so you either need to use dynamic arrays(hence heap) or increase the stack size in the compiler settings.
