      //Goofus and Gallant swim for the same amount of time when the current water temperature is 80.5.
      //When the starting temperatue is 78, Goofus swims 0 min but Gallant swims 1 min.
      //Gallant just dives right in.
      //Goofus checks the water temperature first.
      //while loop does the action after checking the condition but do-while loop does the action before checking the condition
      //pre-test loop is while loop and post-test loop is do-while loop
