Trouble with opening file in code

[ahhvb]

I am having trouble opening a file after I close it. It is at the point where I verify the file is open, but it keeps telling me file closed. And just as a side note the stars around the code are not in the actual program. It is just there to easily find what I am talking about. I am using the same code that was used to first open. I would appreciate any and all help here.

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

using namespace std;

//function prototypes
double averageScore(int, int, int);
int highestScore(int, int);
int amountA(int, int);

int main()
{
//Declaring variables
string fileName;
ifstream inputFile;
int test1, test2, test3, students = 5, test1Sum, test2Sum, test3Sum;
int highScore = 0, numberA;
double average;
cout << "Please enter the file you wish to open: ";
cin >> fileName;

//Opening file
inputFile.open(fileName.c_str());

//Displaying average score per student
cout << "Average per student: ";
for (int count = 0; count < students; count++)
{
inputFile >> test1 >> test2 >> test3;
average = averageScore(test1, test2, test3);
cout << setprecision(2) << fixed << showpoint;
cout << count+1 << "=" << average << " ";
}
cout << endl;

//Closing and re-opening file
inputFile.close();
inputFile.open(fileName.c_str());

//Display average per test

double average;
cout << "Please enter the file you wish to open: ";
cin >> fileName;

//Opening file
inputFile.open(fileName.c_str());

//Displaying average score per student
cout << "Average per student: ";
for (int count = 0; count < students; count++)
{

cout << setprecision(2) << fixed << showpoint;
cout << count+1 << "=" << average << " ";
}
cout << endl;

//Closing and re-opening file
inputFile.close();
inputFile.open(fileName.c_str());

//Display average per test

//Displaying High Score
while (inputFile >> test1)
{

}

If the stream is already associated with a file (i.e., it is already open), calling this function fails...The function sets failbit in case of failure.

Returns whether an error flag is set (either failbit or badbit).

Look through your code to see where you've violated the requirements for open
