/// both Goofus and Gallant swim for a total of 4 minutes when the temp is 80.
/// if the temp is only 78 they can only swim for one minute.
/// both determine the water temp before diving into the lake.
/// a while loop tests the conidtion before execution until a condition is met, however the do while loop executes the code before checking to see if the condition is met.
/// since the While loop tests the code before execution, it can be referred to as a pre-test loop and a do while loop can also be called a post-test loop by the same logic.
