Program Listing

#include <iostream>

#include <iomanip>

using namespace std;

 float average(float prelim, float midterm, float final)

  {

      float compute=0;

      bool value;

      compute = (prelim * 0.30) +

                (midterm * 0.30) +

                (final * 0.40);

       if (compute >= 75.00) {

         value = true;

       }

       else

       {

           value = false;

       }

       switch(value) {

           case true : cout << "You Passed !!!";

                       break;

           case false : cout << "You Failed";

                       break;

       }

       cout << "\n\n";

       return(compute);

  }

  main() {

      float pre=0,mid=0,fin=0;

  cout << "\tGrade Solver Using Functions in C++";

  cout << "\n\n";

  cout << "Enter Prelim Grade :=> ";

  cin >> pre;

  cout << "Enter Midterm Grade :=> ";

  cin >> mid;

  cout << "Enter Final Grade :=> ";

  cin >> fin;

  cout << "\n\n";

  cout << fixed << setprecision(2);

  cout << "Your average grade is "

       <<average(pre,mid,fin)<<".";

  cout << "\n\n";

  system("PAUSE");
