using a funtion to find the average of test scores

i need help to find the averge of the 4 highest test scores
out of the 5 that were entered i think i need a func but i'm having trouble setting it  up..

#include <iostream>
#include <iomanip>
using namespace std;


void EvalGrade ( int Grade);
void FindAve (float Ave);
void Minimum(float,float,float,float,float);
{
  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";
   cin >> Grade;

   EvalGrade ( Grade);

   cout << "Please enter Test 4\n";
   cin >> Grade;

   EvalGrade ( Grade);

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

    EvalGrade ( Grade);

Sounds like you need a bubble sort to order the grades highest to lowest and then use the first 5 grades.

That way you can enter as many as you like and only then average the best 4 or however many you wish to see.

This is an old routine for sorting most occuring lotto numbers.
MOSTLOTTO is a structure that holds the numbers 1 to 53 and
the amount of times shown for each of the numbers.

struct LOTTO
{
char NumberString[10]; // 1 to 53 for displaying
int   Num; // amount of times shown.
};

LOTTO MOSTLOTTO[10000];

//some other function to read values into MOSTLOTTO
LoadMostLotto();

//bubble sort
void SortMOST(int end)
{
int top, search, temp;
for(top=0;top < end-1;top++)  
for(search=top+1;search < end;search++)  
if(MOSTLOTTO[search].Num > MOSTLOTTO[top].Num)
{
 temp = MOSTLOTTO[search].Num;
 MOSTLOTTO[search].Num = MOSTLOTTO[top].Num;
  MOSTLOTTO[top].Num = temp;
}// end if
}// end for
}// end func


So now if I wanted to I could use only the first 4 elements of MOSTLOTTO to do an average on.

int LottoAverage = (
MOSTLOTTO[0].Num +
MOSTLOTTO[1].Num +
MOSTLOTTO[2].Num +
MOSTLOTTO[0].Num) / 4;



So now your logic would go

(semi pseudo code)

struct YOUSTRUCT
{
....
....
};

YOUSTRUCT YOU[YOURMAX];

begin func
{
begin outer loop
{
clear screen;
Prompt menu "(L)oad, (A)verage, e(X)it"

if(L)
loop
{
YOU[x].Val1=xxxxx;
YOU[x].Val2=yyyyy;
x++;
prompt (exit) break;
}//endifL

if(A)
{
prompt how many >> in
int val=0;
int x=0;
adding loop
{
add from YOU[x].yyy or xx to val ,then x++ untill x== in
}//end adding loop
answer = val / in;
}//endif A

if(X)break;

}//end outer loop

}//endfunc
