//The following has been sellected as the best solution to the bad.cc problem
//My reasons will be put as comments like this //RJB...  Dr. R Botting
/*
  Lab 03 assignment of BAD.CC.
  Programmer:  John P. McDaniel
  Revision Date: 17 Apr 95
  Program name: Averages.
  Saved as: good.cc
//RJB  John took the trouble to document the code.
//RJB  This program is going to be changed several times so it is worth it.
--------Problem-----------
  Get five inputs and compute the average for output.

--------Analysis-----------
  Get five inputs.  Calculate the average of the five inputs by adding all
five values and dividing by the number of the values.

 Data Types
 const int total_grades = 5
//RJB  It is always worth naming every constant value in a program with
//RJB  the exception of 0, 1 and -1 perhaps.
//RJB  Nitpick:  it should be called number_of_grades or some such

 Input
 double grade1, grade2, grade3, grade4, grade5
//RJB  Fixes problem of decimal input
//RJB  Does not assume that we know what the grades are

 Output
 double grade_ave

 Formulae
 grade_ave = (grade1 + grade2 + grade3 + grade4 + grade5) / total_grades

----Design---------
  Initial Algorithm

1. Output instructions.
2. Get inputs.
3. Calculate average.
4. Print output.

  Refinements
2.
 1. grade_ave = (grade1 + grade2 + grade3 + grade4 + grade5) / total_grades

----Program Implementation-------
 */

#include <iostream.h>

int main ()
{
  //Declaring the constant.  The number of grades to be averaged.
  const int total_grades = 5;

  //Declaring the variable inputs for the grades and the variable output.
  double grade1, grade2, grade3, grade4, grade5, grade_ave;

  //Output instructions
  cout << "\nThis program averages five grades.  Please input each grade\n"
       << "value and press return.\nStart inputing values now.\n";

  //Input the five grades.
  cin >> grade1 >> grade2 >> grade3 >> grade4 >> grade5;

  //Calculate the average of the five grades.
  grade_ave = (grade1 + grade2 + grade3 + grade4 + grade5) / total_grades; 
   
  //Producing the result to output.
  cout << "\nThe average is " << grade_ave << ".\n\n";

  //Returning the error code of zero for 'Worked fine'.
  return 0;
