Thread: Need Help with While Loop Lab

I am struggling with this program that wants to ask the user how many grades they wish to enter, have the user enter each grade, then determine the average of all the grades. I am stuck with getting the average to computer correctly... Can you guys check to see what I am missing in my code?

int main()
{
    //No Local constants
    int counter = 0; //While Loop counter
 
    //Local variables
    int totalGrades; //Max number of loop executions
    int runningTotal; //Running total of loop counter
    int grade;
    int average; //Average of grades
          char endProgram; //Pause screen
 
    /*************** Begin main Function Executables *****************/
 
    //Clear the screen
    system ("cls");
 
    //Prompt user for number of grades they want to enter
    cout << "How many grades would you like to enter?   ";
    cin >> totalGrades;
 
   while (counter < totalGrades) //stop when counter equals value of totalGrades
   {
         runningTotal = counter + grade;
         cout << "Please enter the next grade --->  ";
         cin >> grade;
         counter = counter + 1; // increase counter by 1
 
   } //end while loop
 
   average = runningTotal / totalGrades; //compute average
   cout << average << " is the average of the grades entered." << endl;
 
    //Pause to read output
    cout << "\n\n"; //skip 2 lines
    system("pause");
 
    //Indicate to OS successful termination of program
    return 0;
 
}//end main

Sorry about that... Can anybody help with this?
