C# - Part 14 - Do While Loop - Tutorial For Beginners

In this video we will be learning about do while loop in C# Timestamps -- 00:00 Intro 00:22 Do while demo 06:09 While vs Do While The do-while loop in C# is similar to a while loop, but with a key difference: guaranteed execution at least once. Here's the breakdown: Do-while Structure: It uses the keywords do and while. The code block comes first, enclosed within the do block. Initial Execution: Unlike a while loop, the do-while loop executes the code within the do block at least once, regardless of the initial condition. Condition Check: After the code executes, the loop checks the while condition. If the condition is true, the loop repeats, executing the code again. Update and Repeat: Similar to a while loop, the control variable typically gets updated after each iteration. Then, the condition is checked again. Loop Termination: The loop continues as long as the while condition remains true. Once the condition becomes false, the loop terminates. Think of it like this: Imagine you absolutely have to taste a bite of cake (initial execution), but only if you like it (condition check). If you do, you go for another bite (code execution and update). This cycle continues as long as you enjoy the cake (condition true). Here's the key point: The do-while loop ensures the code executes at least once, even if the condition is initially false. This can be useful in situations where some initial action is necessary before checking the loop's continuation.
