/*
   Average Rainfall
   
      Write a program that calculates the average monthly rainfall for three months. The
      program should ask the user to enter the name of each month, such as June or July, and
      the amount of rain (in inches) that fell that month. The program should display a
      message similar to the following:
      The average monthly rainfall for June, July, and August was 6.72 inches.
