I CAN NOT GET THIS TO WORK I THINK IT IS GOING WRONG IN THE INDATE FILES

#include <iostream>
#include <fstream>
#include <string>
#include <iomanip>
#include <cstdlib>

char calculateGrade (double);
int main ()
{
char grades [15];
double avg, average=0;
int count=0;
string name;

ifstream inFile;
ofstream outFile;
cout << "\n\tProgram that works with files and functions.";
cout << "\n\n\tEnter the input file name : ";
cin >> grades;
inFile.open("G:\\grades.txt");

if (!inFile.is_open("G:\\calGrades.txt"))
{
	cout << "\n\n\tError with the input file";
		exit (0);

lines 24 and 33: is_open() does not take any parameters.

line 30: you can not put string literal on that line. You have to replace that string literal with a variable name, something similar to what you did on line 21.

There are probably other errors -- I stopped reading your code there.
