Question

#include<stdio.h>

int main()
{
    struct value{
       int bit1 : 1;
       int bit3 : 4;
       int bit4 : 4;
       }bit={1,2,2};
     printf("%d %d %d\n",bit.bit1,bit.bit3,bit.bit4);
     return 0;
}

Output :

-1 2 2

Please explain the oupput of the program ?

Answer 1

Presumably the only curious output is the first one.

Well, consider the range of values that a 1-bit two’s-complement integer can represent.
