Segmentation fault on large array sizes

Question

The following code gives me a segmentation fault when run on a 2Gb machine, but works on a 4GB machine.

int main()
{
   int c[1000000];
   cout << \"do         


        

Answer 1

Because you store the array in the stack. You should store it in the heap. See this link to understand the concept of the heap and the stack.
