C in 100 Seconds: while vs do-while — Two Ways to Loop | Episode 7

C has two kinds of while loops and they behave a little differently. The regular while loop checks the condition before running anything — if it's false from the start, the body never executes. do-while flips this around — it runs the body first, then checks. That means it's guaranteed to run at least once. Count up with while, count down with do-while. Same idea, different timing.
