Sentinel Value & Float Variables

[Huppa]

I want to add a line that will count how many grades are 93 or over and output the count. How could I go about doing so?

//grade2.cpp
//Class avg. w/ sentinel-controlled rep.

#include <iostream.h>
#include <iomanip.h>

           
   int main()
           
   {
      int total, gradeCounter, grade;
      float average;
   
   //Initialization 
      total=0;
      gradeCounter=0;
   
   //Processing
      cout << "Enter grade, -1 to end: ";
      cin >> grade;
   
      while (grade != -1) {
         total = total+grade;
         gradeCounter=gradeCounter + 1;
         cout << "Enter grade, -1 to end: ";
         cin >> grade;
      
      }
   
   //Termination
      if(gradeCounter != 0) {
         average=static_cast< float > (total)/gradeCounter;
         cout << "Class average is " << setprecision(1)
            <<setiosflags(ios::fixed | ios::showpoint)
            <<average << endl;
         cout << gradeCounter << " grades were entered.";
      
      }
      else
         cout << "No grades were entered" << endl;
   

      return 0; 
   
   }

The line you want is topGradeCounter += (grade >= 93) ? 1 : 0;

 
int topGradeCounter = 0;

...

while (grade != -1) {
total = total+grade; 
gradeCounter = gradeCounter + 1; 
topGradeCounter += (grade >= 93) ? 1 : 0;

nicer code:

while (grade != -1) {
total += grade; 
gradeCounter++; 
topGradeCounter += (grade >= 93) ? 1 : 0;

Thank you very much.
