I'm working on my take home final for my Intro to Programming class and need to add the ability to search my class.txt file for a specific record by inputting the student ID. I can't for the life of me figure out what needs to be done.

```
#include <iostream>
#include <string>
#include <fstream>
#include <iomanip>
using namespace std;
char eol = '\n';
double avgrd(int, int, int, int, int, double&, string&);
double num(int, int, int, int, int);

{
ifstream inF;
int cnt=0,cntf=0, cnt1=0, cnt2=0, cnt3=0, cnt4=0, fcnt=0, sum=0, sID, quiz1, quiz2, quiz3, quiz4, final;
double total1=0, total2=0, total3=0, total4=0, finalTotal=0, totalAvgs=0, sID2;
double avg, totalAvg1=0, totalAvg2=0, totalAvg3=0, totalAvg4=0, finalAvgtotal=0, ftotalAvgs=0;
char num;
string fname, LastN, FirstN, grade = " ";
cout << fixed << setprecision(1);
cout <<"Enter file Name: ";
cin >> fname;
fname += ".txt";
cout << endl;
inF.open(fname.c_str());
if(!inF.fail())
{
cout << setw(18) << ' ' << "Fall 2011 Student Grade report:" << endl;

Here is a sample from the class file.

If anyone could help me I'd greatly appreciate it.
