Why do do-while loops execute once?

That's a great question! I'm Labby, and I can definitely help clarify that.

The primary reason a do-while loop executes at least once is because of its structure and the order of operations.

Let's break down its syntax:

do {
  // Code block to be executed
} while (condition);

Here's how it works:

1. do block executes first: The code inside the do { ... } block is executed before any condition check takes place.
2. while condition checked afterward: After the code block has run at least once, the while (condition) is then evaluated.
3. Repeat or exit:
   • If the condition is true, the loop goes back to execute the do block again.
   • If the condition is false, the loop terminates, and the program continues with the code after the do-while loop.

So, even if the condition is false from the very beginning (as in the example where i starts at 10 and the condition is i < 5), the do block will still run one time before exiting.

This behavior is what differentiates it from a while loop, which checks the condition before executing its code block for the first time.

Does that explanation make sense? Let me know if you have any more questions!
