What are while loops in C++?

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

Sure! A while loop in C++ repeatedly executes a block of code as long as a specified condition is true.

How do I write a basic while loop?

You can write a basic while loop like this:

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

This will print numbers 0 to 4.

What happens if the condition is never false?

If the condition never becomes false, the while loop will create an infinite loop, which can cause your program to hang.

Can you give me an example of an infinite loop?

Certainly! An infinite loop can be created like this:

while (true) {
    std::cout << "This will run forever!";
}

Make sure to have a way to exit such loops!
