c++ - Const variable changed with pointer in C

Question

The variable i is declared const but still I am able to change the value with a pointer to the memory location to it. How is it possible?

int main()
{

    const int i = 11;
    int *ip = &i;
    *ip=100;
    printf("%d
",*ip);
    printf("%d
",i);
}

When I compile, I get this warning :

test.c: In function ‘main’:
test.c:11: warning: initialization discards qualifiers from pointer target type

Output is this

100
100

Answer 1

const is a compile-time feature.
It doesn't prevent you from shooting yourself in the foot; that's what the warning is for.
