Iteration Quick Guide

Type	Application	Example	Notes
do while	repeat actions at least once		the initialization expression can also be the update expression, since the body executes before evaluating the controlling expression the controlling expression comes after the loop body the update expression is inside the loop body
for	repeat actions a certain number of times		the initialization, controlling, and update expressions are all part of the loop setup they go in the parentheses before the loop body
while	any other circumstances!		the initialization expression is definitely before the controlling expression the controlling expression comes before the loop body this means it is possible that the loop body does not even execute once! the update expression is inside the loop body
