5 while Loop Repeatedly execute an instruction or set of instructions as long as (while) a certain condition is met (is true) Repeat A while X is true As soon as X is no longer true, break out of the loop and continue on to B A may never execute A may execute only once
In this when and while worksheet, students learn and practice three rules associated with using 'when' and 'while' with the past simple and past continuous. Students begin by completing two grammar rules and examples for using the past simple and past continuous with 'when' and 'while'.
While is used to express two actions happening at the same time. (A) One of the actions is shorter than the other (and possibly) interrupts the other. OR (B) The duration of both actions takes a noticeable amount of time, and happen simultaneously.
In this section we give a more detailed semantics for While which describes, at least indirectly, this sequence of basic operations which should be performed in order to execute a given command. The judgements in the small-step semantics for While take the form hC; si ! hC0 ; s0i meaning:
The While Loop We introduce an alternative to the for-loop called the while-loop. The while loop is more flexible and is essential for ``open ended’’ iteration.
