Chapter 8, Problem 2D
Program Plan Intro
Boolean algebra:
- It defines the rules for working with the set {True, False}.
- The “and”, “or”, “not” are the Boolean operators.
- The logical “and” is used to evaluate two expressions in order to obtain a single relational result. It returns the Boolean value “True” when both the operands are true, otherwise returns “False”.
- The logical “or” is used to evaluate two expressions in order to obtain a single relational result. It returns the Boolean value “true” when one of the operands is “true”. It returns “false” only if both the operands are “false”.
- The logical “not” is used to reverse the input value.
