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.
