Let x be an integer which can take a value of 0 or 1. The statement if (x == 0) x =1 ; else x =0 ; is equivalent to which one of the following ?

A x = 1 +x ;
B x =1 -x ;
C x =x -1 ;
D x = 1 % x;

Correct Answer: x =1 -x ;

Consider the option: x = 1 - x. Consider x = 0 ; x = 1 - 0 = 1 = > So when x = 0 we get x value to be 1. Consider x = 1 ; x = 1 - 1 = 0 = > So when x = 1 we get x value to be 0.
