Another elem entary program m ing concept is the while control structure, which is a type of loop. A program m er will often want to execute a set of instructions m ore than once. A program can accom plish this task through looping, but it requires a set of conditions that tells it when to stop looping, lest it continue into infinity. A while loop says to execute the following set of instructions in a loop while a condition is true.
