How do you define a boolean in c

WebLike any other variable, we can declare C++ boolean type using a bool keyword followed by the name of the variable itself. C++ boolean variables can be initialized by assigning integer values to them or by special keywords called boolean literals. The latter ones are represented in C++ with keywords true/false, and their type is bool. WebBoolean algebra can be defined as a type of algebra that performs logical operations on binary variables. These variables give the truth values that can be represented either by 0 or 1. The basic Boolean operations are conjunction, disjunction, and negation. The logical operators AND, OR, and NOT are used to represent these operations respectively.
