Non-const declaration of array

My compiler gcc allows

int n = 5;
int a[n];

Other compiler visual c gives error. It says array of size 0 cannot be created. Which compiler is correct?

Both are correct... these are compilers... In fact, std C assumes the size of a static array needs to be fixed and set by a constant value. use Define instead, or use malloc for dynamic arrays
