What is the output of this C code?   

 int main()
    {
        if (7 & 8)
        printf("Honesty");
            if ((~7 & 0x000f) == 8)
                printf("is the best policy\n");
    }

 

  • A.Honesty is the best policy
  • B.Honesty
  • C.is the best policy
  • D.No output

Answer: C

Correct answer: is the best policy

Take the two conditions separately.

  • 7 & 8: \(0111 \;\&\; 1000 = 0000\). They share no set bit, so the value is 0 and Honesty is not printed.
  • ~7 & 0x000f: \(\sim 0111 = \ldots 11111000\); masking with \(1111\) leaves \(1000 = 8\), which does equal 8.

So only the second printf runs, and the output is is the best policy.
