C++ Boolean Data Types

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)

Try it yourself!

Boolean values are mostly used for conditional testing, which you will learn more about in a later chapter.
