Grade Brackets in C++

In this article  I would like to share with you a sample program that I wrote for my class in C++ programming 6 years ago to check and determine the grade brackets of the students using two dimensional array in C++. The code is very simple and easy to understand I hope you will find my work useful in learning C++ programming.

Program Listing

#include <iostream>

using namespace std;

 main()

{

    double grades[5][2];

    int row=0,col=0, count=0, count2=0;

    int count3=0, count4=0;

    cout << "\t Grade Bracket Version 1.0 ";

    cout << "\n\n";

    // Ask for 10 grades

    for(row= 0 ; row < 5 ; row++){

     for (col=0; col <2; col++) {

       cout<< "Enter grades :=>";

       cin >> grades[row][col];

    }

    }

   for(row= 0 ; row < 5 ; row++){

     for (col=0; col <2; col++) {

      if(grades[row][col] >= 90){

         count++;

      }

      if(grades[row][col] >= 80 && grades[row][col] <90)

       {

        count2++;

       }

    if(grades[row][col] >= 75 && grades[row][col] < 80)

       {

        count3++;

       }

   if(grades[row][col] < 75)

      {

       count4++;

      }

    }

   }

    //display

    cout << "\n====================";

    cout << "\n     RESULTS        ";

    cout << "\n====================";

    cout << "\n\n";

    cout<<"\nGrades >=90    is: " <<count;

    cout<<"\nGrades 80 - 89 is: " <<count2;

    cout<<"\nGrades 75 - 80 is: " <<count3;

    cout<<"\nGrades < 75    is: " <<count4;

    cout << "\n\n";

    system("pause");
