1. 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 = 1 +x ;
  • D. x = 1 +x ;

Answer: Option B

Explanation:

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.
