Question

What do the following expressions evaluate to?

1. true && false
2. true || false
3. !(5==5)

Answer 1

The expressions evaluate to false, true, and false respectively.

Step-by-step explanation:

1. true && false evaluates to false. The && operator is the logical AND operator, which returns true if both operands are true, and false otherwise. In this case, since one of the operands (false) is false, the expression evaluates to false.

2. true || false evaluates to true. The || operator is the logical OR operator, which returns true if at least one of the operands is true. In this case, since one of the operands (true) is true, the expression evaluates to true.

3. !(5==5) evaluates to false. The ! operator is the logical NOT operator, which negates the value of the operand. In this case, the operand is the equality comparison 5==5, which is true. Therefore, negating true results in false.
