i thought the section name was Teaching , and not google it

 

There is tons of good material for this kind of basic question around. It is a different topic if you are asking for something that wasn't answered hundreds of times on the net.

Edit: You can even find tons of video tutorials about it:

A loop is a process that continues over and over again. When we use loops in programming we are iterating through a piece of code or multiple lines of code until a condition is met. The condition met tells the computer when to stop looping.

With a for loop:

for (int i = 0; i < 10; i++)
{
print(i);
}

the for loop reads: for variable i assigned to 0; for as long as i is less than 10, print i, then increment i by 1.

This will loop till i is no longer less than 10. Now i = 1, is 1 less than 10? So loop the code, and increment. does that 8 more times. i = 10. is 10 less than 10? No, so the loop stops.

While(CONDITION)
{

}

The while loop is a loop that loops while a condition is met.

ex:

while(true)
{
//code
}

This is an example of an infinite game loop. While true, we want to run the code. The problem with this, is that true is never false, thus the while loop runs for ever and will crash your system. You typically do while loops for spawn managers. Check out my tutorial series for some examples.

Do-While loop.

do
{
i++
}while(i < 5);

This loop will run always at least one time, and then the while loop is a condition. So for instance, do this code, while i is less than 5.

It will run through this code 5 times till i is no longer < 5.

This is a very brief explanation of how loops work. I suggest checking out some youtube videos or documentation online.
