Question

Consider the following C program

     

Which of the following represents output of above program ?

Answer 1

Output of the above program : 2 2

p = -3;

q = 2;

r = 0;

s = ++p  && ++q || r++;

s =  -2 && 3 || 0      (    true && true || false   =  true  ( Left to right  ) )  

Hence s = 1

Now  t = p + q + s++  

t = -2 + 3 + 1     = 2

Now s become 2 , post increment  

So , s = 2 and t = 2.

Comments

But MADE EASY Solution says output will be:

    1   2

I don't think so ,as per my knowledge

Logical and (&&) of two integer numbers will be zero , if atleast one of them equals to zero, 

And logical OR of two integer numbers will be zero , if both the number equals to zero

s = ++p && ++q || r++  always return 1.

You can check the expression on any compiler with their actual value  :
