//Gallant and Goofus swim for the same amount of time if the water temp starts at 80.5.
// Gallant swims for zero minutes and Goofus swims for one minute when the water temp starts at 78.
//Gallant checks the water temp first.
//Goofus dives right in.
//A do while loop will is an easier way of doing a while loop.
//The pre-test loop tests the loop before starting. the post-test loop tests after testing.
