Learn C++ for free with this interactive course, and get a handle on one of the most popular programming languages in the world.

You'll start with a simple hello world program and proceed to cover core concepts such as conditional statements, loops, and functions in C++, before moving on to more advanced topics like inheritance, classes, and templates, along with much more.

By the time you're done, you'll be an intermediate level C++ developer, ready to take on your own projects.

Learn C++ from Scratch

​**Loops** allow a programmer to execute the same block of code repeatedly. We will make heavy use of [conditional statements](https://www.educative.io/courses/learn-cpp-from-scratch/comparison-operators) in this section.

## The while Loop

The `while` *loop* is really the only necessary repetition construct. The `for` loop, [coming up](https://www.educative.io/courses/learn-cpp-from-scratch/for-loop), can be duplicated using a `while` loop, and with more control. A simple negation can perform the same behavior as *do-while* loop.

The syntax is as follows:

This lesson introduces the while and do-while loops in C++. It uses coding examples to show their implementation and explain their workings.
