Boolean Types
A boolean data type is declared with the bool keyword and can only take the values true or false .
When the value is returned, true = 1 and false = 0 .
Example
bool isCodingFun = true;
bool isFishTasty = false;
cout << isCodingFun;
// Outputs 1 (true) cout << isFishTasty; // Outputs 0 (false)Boolean values are mostly used for conditional testing, which you will learn more about in a later chapter.
