Self Doubt

Question

#include <stdio.h>

int main()
{
    int b= 14;
    
    b = b + ~b;
    
    printf("op = %d",b);

    return 0;
}

I am gettiing -1 as output why is that so?

Comments

assume int is of 8bit,

then 14 = 0000 1110

bitwise complement of 14 will be 1111 0001

and what's 1111 0001?

-15 in 2's complement representation
