C++ While Loop

This lesson is part of C++ · All levels

Summary

This lesson discusses the repetition while that executes a block of code during a value condition. It is suitable for use when the number of repetitions is not known at the beginning, for example reading the input until the user presses a certain number. You also learn to keep the loop running without limits.

Key points

While executing blocks while the conditions are met.
The control variable must be updated to allow the loop to reach a stop point.
Blocks are not executed at all when the initial condition is already present.
Common mistake: forget the increment so that there is an infinite loop.
