AP CSA Unit 3 Boolean Expressions

Front

Consider the code assuming that a b c and d are ints, which of the following is an example of short circuit evaluation? if a > b is true it doesn't evaluate c == d, if c == d is false it evaluates a > b, if a > b is false it doesn't evaluate c == d, if c == d is true it doesn't evaluate a > b

Back

if a > b is false it doesn't evaluate c == d
