Question

Which output returns the Boolean value FALSE? A: 3 B: 2 C: 1 D: 0

Answer 1

The answer is D: 0

Boolean variables are variables that have two possible outcomes only: true (1), and false (0). Boolean values are not stored as the words true or false. They are stored as integers: true becomes the integer 1 and false becomes the integer 0. Boolean values evaluate to integers 0 (false) or true (1).

Answer 2

D) 0. Any non-zero value is usually considered TRUE, whilst 0 is FALSE.
