What is a do-while loop in programming?

What is a do-while loop in programming?

A do-while loop is a control flow statement that executes a block of code at least once and then repeats the loop as long as a specified condition is true.

Can you give me an example of a do-while loop?

Sure! Here's a simple example in JavaScript:

let count = 0;
do {
    console.log(count);
    count++;
} while (count < 5);

This will print numbers 0 to 4.

What is the difference between a do-while loop and a while loop?

The main difference is that a do-while loop guarantees that the code block will execute at least once, while a while loop may not execute at all if the condition is false from the start.

When would I use a do-while loop instead of a while loop?

You would use a do-while loop when you need to ensure that the code inside the loop runs at least once, such as when prompting a user for input.
