Controlled with While and Do-While Loops: Pseudocode Critical Review A repetition structure causes a statement or set of statements to execute repeatedly. Repetition structures are used to perform the same task over and over. Repetition structures are commonly called loops A condition-controlled loop uses a true/false condition to control the number of times that it repeats. The general structure of a While loop with a condition-controlled statement is: //Declare loop control variable While condition
