What will the output of following C code?
main()
{
int i=0;
while(+(+i--)!=0)
i-=i++;
printf("%d",i);
}

A.    0 Wrong Right

B.    -1 Wrong Right

C.    -2 Wrong Right

D.    1 Wrong Right

Answer : -1

Explanation : Unary + is the only dummy operator in C. So it has no effect on the expression and now the while loop is, while(i--!=0) which is false and so breaks out of while loop. The value –1 is printed due to the post-decrement operator.

}

A.    No output Wrong Right

B.    Error Wrong Right

C.    Compiler Error Wrong Right

D.    Strings are not equal Wrong Right

Answer : No output

Explanation : Ending the string constant with \0 explicitly makes no difference. So “some” and “some\0” are equivalent. So, strcmp returns 0 (false) hence breaking out of the while loop.
