Question

Consider the following C program:

 

Which of the following represents output of above C program?

A)1, 0

B)2, 0

C)1, 1

D)2, 1

Answer 1

Option C

Here, always the OR operator is evaluated Left to right , If left side returns true it wont evaluate the right expression because eventually the answer will be True; It does right check only when the Left side returns False.

So when a++ happens it will give 1 resulting the OR operation to be True so C = 1 and b wont be evaluated so

at final :-   C = 1,B = 1, A = 2

Answer 2

C because first right hand side of expression is calculate then assignment is done
