Looping

Looping is when you want to do something many times.
For example you want to output a 5 times.

for(int iteration = 1; i < 5 ; i++){
       cout << "a";
}

*note :
i++ is equal to i = i + 1

The first is initial statement. If you don't need if just skip it, but always put semicolon (;).

int iteration = 1;
for(; i < 5 ; i++){
       cout << "a";
}

The second is the condition to break from the loop.
The last is the statement that happen after each iteration.
