{
  char letterGrade;
please email me a911hoe@msn.com with answ
 

   switch ( Grade/10)
   {
      case 10:
        case 9:
           
              letterGrade = 'A';
                break;

        case 8:
                 letterGrade = 'B';
                 break;

        case 7:
                letterGrade = 'C';
                break;

        case 6:
                letterGrade = 'D';
                break;

        case 5:
        case 4:
        case 3:
        case 2:
        case 1:
        case 0:
                letterGrade = 'F';



   }

   cout << "The letter grade is: " << letterGrade << endl;
   cout << "The Average is :" << ave << endl;
}

void main()

 {

     float Minimum(float test1,float test2, float test3, float test4, float test5)

         if (test1 < test2 && test1 < test5)
                return test1;
          if (test2 < test1 && test2 < test5)
               return test2;
          if (test3 < test1 && test3 < test5)
               return test3;
          if (test4 < test1 && test4 < test5)
               return test4;
          if (test5 < test1 && test5 <test4)
               return test5;

      FindAve

        Ave = test1 + test2+ test3 +test4 + test5 - Minimum / 4;
     
     return Ave


  int Grade;

   cout <<"Please enter Test 1\n ";
   cin >> Grade;

   EvalGrade ( Grade);

   cout << "Please enter Test 2\n";
   cin >> Grade;

   EvalGrade ( Grade);

   cout << "Please enter Test 3\n";

   EvalGrade ( Grade);

   cout << "Please enter Test 5\n";
   cin >> Grade;

    EvalGrade ( Grade);

tbel000, I don't understand why you now have 3 questions asking about the same problem. Please keep working with the other experts who helped you in the last 2 threads and get things straightened out. They also need to receive credits for helping you as well. Please close two of these open questions as I suggested in the other thread.

correction change last 3 lines with this. aftre min = Minimum(......);

Ave =(float)(test1 + test2+ test3 +test4 + test5 - min) /((float) 4);
        cout.setf(ios::showpoint);
   cout << "The Average is : " << Ave << endl;

here's a real nice way to do it. you won't beleive how short this thing is.

#include <vector>
#include <algorithm>
#include <numeric>

...

int main()
{
    float tmp;
    vector<float> grades = new vector();

    for(int i = 1; i < 6; i++)
    {
        cout << "Please enter Test " << i << "\n";
        cin >> tmp;
        grades.push_back(tmp);
    }

    float total = accumulate(grades.begin(), grades.end(), 0);
    float minimum = min_element(grades.begin(), grades.end());

    float average = (total - minimum) / 4.0;
}
