What are do-while loops in C++?

Can you explain what do-while loops are in C++?

Sure! A do-while loop in C++ 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.

How does it differ from a regular while loop?

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

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

Of course! Here's a simple example:

int i = 0;
do {
    std::cout << i << " ";
    i++;
} while (i < 5);

This will print numbers 0 to 4.

What happens if the condition is false initially?

In a do-while loop, the code inside the loop will still execute once before checking the condition. So, it will run at least one time regardless of the condition.
