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)

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