Help with void function output

[Deathtotock]

I am inputing from a file and I am outputting to a file. well when i run the program it just puts the headers up there and no names or grades. This is the input.

Balto		        85	83	77	91	76
Mickey	  	80	90	95	93	48
Minnie		78	81	11	90	73
Doc		        92	83	30	69	87
Goofy		23	45	96	38	59
Duckey		60	85	45	39	67
Grumpy		27	31	52	74	83
Sunny		93	94	89	77	97
Piggy		79	85	28	93	82
Pluto		        85	72	49	75	63

However, this is the output im getting:

Student    Test1     Test2   Test3   Test4   Test5   Average Grade

And thats it.

Here is my code:

 #include <iostream>
 #include <stdlib.h>
 #include <iomanip>
 #include <string>
 #include <fstream>

using namespace std;



void calculateAverage(double test1, double test2, double test3, double
test4, double test5, double& studentAverage);
int calculateGrade(double grade);

int main()
{

string studentName;
int numberOfStudents = 0;
double classAverage = 0;
double studentAverage = 0;
double totalAverage = 0; //To add the average of all student averages
char grade;
double test1, test2, test3, test4, test5;

ifstream inFile; // input stream variable for the student file
ofstream outFile; // output stream variable

inFile.open("inGrade.txt");
outFile.open("FinalGrades.txt");

cout << setfill(' ') <<setiosflags(ios:: left) << setw(11) <<
"Student" << setw(10) << "Test1"
<< setw(8) << "Test2" << setw(8) << "Test3" << setw(8) << "Test4"
<< setw(8) << "Test5"
<< setw(8) << "Average" << setw(8) << "Grade" <<endl;

outFile << setfill(' ') <<setiosflags(ios:: left) << setw(11) <<
"Student" << setw(10) << "Test1"
<< setw(8) << "Test2" << setw(8) << "Test3" << setw(8) << "Test4"
<< setw(8) << "Test5"
<< setw(8) << "Average" << setw(8) << "Grade" << endl;


if (!inFile)
{
cout << "Unable to open the file." <<endl;
return 1;
}

while(inFile)
{
outFile.setf(ios::fixed, ios::floatfield);
outFile.setf(ios::showpoint);
outFile << setprecision(2);

inFile >> studentName >> test1 >> test2 >> test3 >> test4 >> test5
;

calculateAverage(test1, test2, test3, test4, test5,
studentAverage);

grade = calculateGrade(studentAverage);

cout << setfill(' ') << setiosflags(ios::left) << setw(11) <<
studentName << setw (10) << test1
<< setw(8) << test2 << setw(8) << test3 << setw(8) << test4
<< setw(8) << test5 << setw(9) << studentAverage << setw(8) <<
grade<<endl;
outFile << setfill(' ') << setiosflags(ios::left) << setw(11) <<
studentName << setw (10) << test1
<< setw(8) << test2 << setw(8) << test3 << setw(8) << test4
<< setw(8) << test5 << setw(9) << studentAverage << setw(8) <<
grade<<endl;

totalAverage = totalAverage + studentAverage;

numberOfStudents++;
classAverage = totalAverage / numberOfStudents;
}


outFile << endl << setprecision(2)<< "Class average is:" <<
classAverage << endl;

inFile.close();
outFile.close();

system("PAUSE");
return 0;
}



//function to calculate the average
void calculateAverage(double test1, double test2, double test3, double
test4, double test5, double& studentAverage)
{

studentAverage = static_cast<double>(test1 + test2 + test3 + test4
+ test5) / 5.0;

}




int calculateGrade(double studentAverage)
{
char grade;

if (studentAverage <= 100 && studentAverage >= 90)
grade = 'A';
else if (studentAverage < 90 && studentAverage >= 80)
grade = 'B';
else if (studentAverage < 80 && studentAverage >= 70)
grade = 'C';
else if (studentAverage < 70 && studentAverage >= 60)
grade = 'D';
else if (studentAverage < 60 && studentAverage >= 0)
grade = 'F';
else
cout << "Invalid grade " << endl;

return grade;

}

Any help would be greatly appreciated. Thanks.

I'm not sure. The code works fine for me and writes all the data to the file. Maybe the program is not able to open the inGrade.txt file. How about putting a system("PAUSE") before the return so you can check:

if (!inFile)
{
    cout << "Unable to open the file." <<endl;
    system("PAUSE");
    return 1;
}

I hope this helps solve the problem.

if(!inFile)

That's not the way to check if the file is open.This call is same as calling ifstream::fail( ) which checks if there was a fail bit(generally some file access error) or bad bit(checks to see if stream has lost it's integrity).To check if the file is open use:

ifstream::is_open()

if(inFile.is_open==false)
{
....
}
