Loop structures: Difference between revisions

 

An [[:Category:Iteration|iterative loop]] repeatedly executes a set of instructions as the iterator steps through a series of values. Types of iterative loops include [[forloop]]s and [[foreach]] loops. An iterative loop is a repetition but with a variable dependent on the current iteration. This allows the looped procedure to vary slightly between iterations. For example, the same operation can be carried out on each iteration, but each time on a different object.

 

;Conditional loops:

A [[conditional loop]] tests for a condition around the loop, and repeatedly executes a block of [[instruction]]s whilst the [[condition]] is true. Types of [[conditional loop]]s include [[while]] loops and [[until]] loops.
