Average grade ?

[dkarayof]

This is part a of a 3 part assignment, and im not sure why it isn't returning the correct average.

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

bool GetStudent(char Name[]);
int InputData(char Name[][15], double Grade[]);
void OutputData(int N, char Name[][15], double Grade[]);

int main()
{
  int Count;
  char Name[10][15];
  double Grade[10];


  Count = InputData(Name, Grade);
  OutputData(Count, Name, Grade);

  cout << "\n\n";
  return (0);
}

int InputData(char Name[][15], double Grade[])
{
  int i=0;

  while(GetStudent(Name[i]))
  {
    cout << "What is " << Name[i] << "'s grade? ";
    cin >> Grade[i++];
  }

  return --i;
}

bool GetStudent(char Name[])
{
  char YN;

  cout << "\nDo you want to enter a new student? (Y/N) ";
  cin >> YN;
  if(YN > 90)
    YN -= 32;

  if(YN != 'Y')
    return false;
  else
  {
    cout << "\nWhat is the student's name? ";
    cin >> Name;
    return true;
  }
}

void OutputData(int N, char Name[][15], double Grade[])
{
  int i;
  double sum=0;

  cout << "\n";
  for(i=0; i<=N; ++i)
{ 
	sum += Grade[i];
  }
      double avg = sum /N;

    cout << setw(16) <<Name[i] << setw(4) << Grade[i] << "\n";
	cout <<"\nThe total average is: " << avg;

  return;
}

What data are you inputting, and what results are you getting?

line 65 change to:
double avg = sum /(N*1.0);



edit:
or the proper way is to static_cast N to a double.
