help with reading a file

[CyberShot]

I am working on reading the contents of a file that looks like this

Larry 4 M 40
Leslee 6 F 99
Mary 9 F 39
Hank 6 M 88
Eden 7 F 71
Drake 5 M 94
Ava 4 F 28
Seth 4 M 11
Renaldo 3 M 77
Carrie 8 F 68

I have been able to read the data in and print it to the screen by doing this

cout << fixed << showpoint << setprecision(2);
	//getting the information for the file
	cout << "Please enter the full path to the file: ";
	getline(cin, inputFileName);
	//Open the input file.
	inputFile.open(inputFileName.c_str());

	//check to see that the file was opened
	if(!inputFile.is_open())
	{
		cout << "Unable to opent the input file" << endl;
		system("PAUSE");
	}
	//set up a while loop to read to the end of the file
	while(inputFile.peek() != EOF)
	{
		getline(inputFile, line);
		cout << line << endl;
	}

my problem is that I am trying to get the data into variable so that I can work with it. I need to add up the scores and average them, So I have taken them in this way

while(!inputFile.eof())
	{
		inputFile >> firstName >> age >> gender >> score;
		cout << firstName << age << gender << score << endl;
	}

that was my test code to see if it is working but it's not printing anything on the screen. I should mention that I am a beginner and I have only been working with this code for 3 days. So if you help, please explain in newbie terms
