///when i change the statring temp to 80.5 they both swim for 4mins.
///when i input 78 as the starting tempurature GALLANT swims for 0 minutes and GOOFUS swims for 1 minute
///GALLANT checks the water first
///GOOFUS just jumps right in then checks
///a while loop checks the condition before =running the code while a do-while loop runs the code on etime before checking the condition
///pre-test loop = while loop, post-test loop = do-while loop
