Join Barron Stone for an in-depth discussion in this video While loops, part of Programming Foundations: Real-World Examples.
- The dishwasher just finished running…so I'm ready to put away the dishes…into the cabinet.…Uh-oh.…Most of the dishes in there look clean, but…this pan had some burnt food stuck to it…that the dishwasher couldn't get off.…I guess I'll have to clean it…the old fashioned way.…The process of scrubbing this pan…belongs in a while loop…because I don't know how many times…I'm going to have to scrub it…to get it clean.…Rather than specifying how many times…I'm going to scrub it before I begin,…like you would with a for loop,…I'll just start scrubbing this pan…and I'll continue scrubbing…until a specific condition is met.…
If the pan's clean…and then I can finally stop.…Each round of the scrubbing…is a two step process.…First, I scrub the pan with a sponge.…Then I give it a quick rinse…so I can see whether or not it's clean.…Now I check it.…Nope, still dirty.…So repeat that process again…and I'll continue this process…on and on and on…until the pan is finally clean.…Now I'm only checking the condition of the pan…at the end of the two step cleaning process.…
