what is bool in c++

In C++, a boolean data type is defined using the keyword bool . A boolean variable can only have two possible values: true or false . In C++, Boolean values declared true are assigned the value of 1, and false values are assigned 0. Any time a Boolean variable is used in C++, it is declaring that the variable can have only one of two possible values: true (1) or false (0) . The most common use of the bool data type is for conditional statements.
