segmentation fault 11 in C++ on Mac

Question

When I try to run this

int N=10000000;
short res[N];

I get segmentation fault 11

when I change to

int N=1000000;
short         


        

Answer 1

You can't allocate all that on the stack. Try short* res = new short[10000000]; and don't forget to clean up.

Alternatively, you can use std::vector res(10000000);
