Iteration

Iteration is essentially looping.

Loops generally involve repeating some code a certain number of times, or until a condition is met.

Types of iteration

There are two main forms of loops in programming languages:

• Count controlled: for loop or foreach loop - see definite iteration.
• Condition controlled: while loop or do while loop - see indefinite iteration.

Iteration and recursion

Recursion is a programming technique that often achieves the same thing as iteration. In some cases, it can be a better option than iteration.
