Welcome back! You've already got a grasp of the while loop and how it helps automate repetitive tasks. Now, we’ll be exploring a different type of loop: the do-while loop. This loop is special because it guarantees at least one execution of its code block before checking the conditional expression. This unit will help you understand how to use do-while loops in C# efficiently, especially when you need to ensure the loop’s code runs at least once before any condition check.

In this lesson, you’ll learn how a do-while loop operates, which is similar to a while loop but with a key difference: the condition is checked after the loop body is executed. We'll break down the syntax and provide a practical example. To give you a peek, here’s a snippet that shows a do-while loop printing mission steps from 1 to 5:

Understanding the do-while loop is important for scenarios where you need to ensure that a block of code executes at least once, no matter what. This can be particularly useful for tasks like prompting a user for input until valid data is entered or running initial setup steps for an application. By mastering the do-while loop, you'll add another powerful tool to your coding arsenal, enabling you to handle specific repetitive tasks more effectively.
