    /*
    1. Gallant and Goofus swim for the same amount of time when the temperature is set to 80.5F. 
    2. Goofus swims but Gallant does not.
    3. Gallant checks the water temperature first, then dives in.
    4. Goofus dives in first, then checks the water.
    5. A while loops initiates after an expression is checked and returns a value of TRUE. A do-while loop will execute its       function once before, then check the condition for the next round. 
    6. Do-while is a post test loop
        While loop is a pre- test loop.
