C++ Switch

This lesson is part of C++ · All levels

Summary

This lesson explains the switch statement as a branching alternative when comparing one variable with many constant values. Every possibility is written in a case, and default is the last option when there is no case matching. The use of a break prevents the execution from falling to the next case.

Key points

The switch is suitable for comparing the values of integers or char accurately.
Each case is terminated break so that there is no fall-through.
The default is optional and executed when there is no suitable case.
The switch can't directly check the range of values like >= and <.
