Bool - Definition

Definition: Bool is a fundamental type in C, C and C# languages. Variables of this type can only take two values- 1 and 0. In C these correspond to true and false and can be used interchangably. In C# bool variables can only use true and false, they are not interchangeable with 1 and 0. Boolean variables can be packed together to save memory space. An understanding of binary can be a useful skill. Note Because of the way false and 0 are usually treated the same (except in C#), any non zero value is the same as true, not just 1.
