Exploring the Differences between Count-controlled Loops and While Loops
August 14, 2014

Count-control loops are performed a specific number of times while While loops are performed based upon whether a condition is true or not. The process of a While loop is based upon a condition which is dependent upon Boolean expressions. For While and Do While loops, if the expression is true the loop is executed. If the condition is false the loop is exited. A While loop is a pretest loop, which means that the condition is tested before performing an iteration. The Do-While loop is a posttest loop meaning that the loop is executed once before the condition is tested. (Gaddis, 2010)
Three reasons a count-controlled loop can be better than a condition-controlled loop include: the fact that it keeps count of the number of times you to input data, it only runs the specific number of times you have instructed the program to, and it will stop after to allotted time instructed.
Three reasons condition-controlled loops are more advantageous than count-controlled loops include the fact that the variable can be more than one number as long as the condition is true, condition controlled loops will only stop when the condition is false (or true as in the case of the Do-Until loop), and the variable numbers can be any real number which will make the statement true.
