Answer 2

The while loop is used to repeat a section of code an unknown number of times until a specific condition is met.

Answer 3

While something is True, do something.

So if you have a program that counts something, you can make it stop at a certian number, otherwise count forever .

Answer 4

It basically says while a certain condition is met execute the given code

For example if we have a variable declared as 5 and we write a while loop to increase the number and print it put:
(not sure if this is a valid while loop it's just to illustrate the concept)

int a = 5;

while (a < 5) {
a++; // increase a's value.
cout << a << endl; // print a's value.
}
This code will print the following:
6
7
8
9

Hope this helps.
