Sample Program Using an Array

//  this program reads 10 grades into an array, then calculates
//  the average grade and the highest grade

#include <iostream.h>
#include <iomanip.h>

int main()
{
   int i;
   int grades[10];
   int sum;
   float average;
   int max;

//  set up output to print floating point values with one dec place

   cout << setiosflags(ios::fixed);
   cout << setiosflags(ios::showpoint);
   cout << setprecision(1);

//  read in the grades and add them up

   sum = 0;
   for (i = 0 ; i < 10 ; i++)
   {
      cout << "Enter grade: " << endl;
      cin >> grades[i];
      sum = sum + grades[i];
   }

//  calculate the average grade

   average = float(sum) / 10;

//  find the highest grade

   max = grades[0];
   for (i = 1 ; i < 10 ; i++)
      if (max < grades[i])
         max = grades[i];

//  print the grades, the average and the highest

   cout << "The grades are: " << endl;
   for (i = 0 ; i < 10 ; i++)
      cout << setw(7) << grades[i] << endl;
   cout << endl << "The highest grade is " << max << endl;
   cout << endl << "The average grade is " << average << endl;
   return 0;
