C++ Booleans

This lesson is part of C++ · All levels

Summary

This lesson discusses the boolean data type that only stores true or false values. The Boolean becomes the basis of all branching conditions and statements in a program, because every comparison always yields a boolean. You also learn to use logic operators to combine several conditions at once.

Key points

The bool type has two values: true (1) and false (0).
Comparison results like >, <, == are always boolean.
The operator && is only valid if both sides are true.
The operator is of the value true when one side is right, and! reverses the value.
