*
* CALCULATE AVERAGE RAINFALL
* ____________________________________________________________
* This program calculates the average rainfall for three months
* based on month names and rainfall amounts.
*
* Computation is based on the formula:
* average = (rainfall1 + rainfall2 + rainfall3) / 3
* ____________________________________________________________
* INPUT
* month1    : Name of the first month (as a string)
* month2    : Name of the second month (as a string)
* month3    : Name of the third month (as a string)
* rainfall1 : Rainfall for the first month (in inches, as a double)
* rainfall2 : Rainfall for the second month (in inches, as a double)
* rainfall3 : Rainfall for the third month (in inches, as a double)
*
* OUTPUT
* average   : The average rainfall for the three months (in inches)
