      //3. Gallant checks the water temperature before diving in.
      //4. Goofus dives in before checking the water temperature.
      //5. The do-while loop checks the parameters after printing and adding to the total, whereas a while loop checks before.
      //5. The do-while loop is a post-test condition and the while loop is a pre-test condition.
