Array index out of bound in C

Question

Why does C differentiates in case of array index out of bound

#include 
int main()
{
    int a[10];
    a[3]=4;
    a[11]=3;//doe         


        

Answer 1

Just to add what other people are saying, you cannot rely on the program simply crashing in these cases, there is no gurantee of what will happen if you attempt to access a memory location beyond the "bounds of the array." It's just the same as if you did something like:

int *p;
p = 135;

*p = 14;

That is just random; this might work. It might not. Don't do it. Code to prevent these sorts of problems.
