need some help with organizing output for students

Okay, I have the basis for the rpogram I am doing, it basically is supposed to read a students info, then output it on the screen, I do not have to organize the output by the student's reference number now, but I wanted to know how I am supposed to do it. I was thinking that i could re-read the input file to recognize each reference number and skip pages in between the two. here is my code, that does the output, but I am not sure what I should do to organize the output by reference number

Code:

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

using namespace std;

int main()
{
	string SSN, LastName, FirstName, ReferenceNum;

	ofstream outFile;
	ifstream inFile;

	outFile.open("a:report.txt", ios::out);
	inFile.open("a:StudentData.txt", ios::in);

	outFile << setw(6) << "Introduction to C"
			<< setw(5) <<"\nTerm: Fall 2002"
			<< setw(5) << "\nRef#"
			<< "\n\n\nSSN" << right << setw(20) << right << setw(20) << "Last"
			<< right << setw(20) << "First" << right << setw(20) << "Reference#\n";

	while (inFile)
	{
	inFile >> SSN >> LastName >> FirstName >> ReferenceNum;
	outFile << right << SSN << right << setw(17) << LastName << right 
			<< setw(16) << FirstName << right << setw(17)<< ReferenceNum << "\n";
	}



	return 0;
}

posted the wrong code before, it's changed now

Yep, but one way to do this is to get the reference number when reading each student's info, and store it into that elenemt of an array (or vector).

Code:

student class[31];
cin >> ref_id >> name >> GPA;
class[ref_id].name = name;
class[ref_id].GPA = GPA;

Then, at the end, output everything in order.
