trying to print a line from a text file

I've got an apparent logic problem that I can't seem to solve. This program should open a text file and search for a terminal and then print the entire line.

It does not work as it should and I can't seem to figure out why.

Code:

/***********************************
*      Pre-Compiler Directives     *
***********************************/
#include <iostream>
#include <fstream>
#include <sstream>
#include <cassert>
#include <string>
using namespace std;

/***********************************
*        Global Variables          *
***********************************/
int terminalNumber;
string inputFileName = "terminals.txt"; // input file name
string lineOfText;
string stringTerminal;
ifstream inStream;
string number;
string output;
string input;

/***********************************
*            Main		   *
***********************************/
int main()
{	
	cout << "This program takes a terminal number\n"
			"and prints out the terminal associated\n"
			"with that number.\n"
			"Enter a terminal to retrieve 1-99 or 0 to quit -->  ";
	cin >> terminalNumber;
	stringstream str;
	str << "terminal" << terminalNumber << endl;
	string stringTerminal = str.str(); // The final string combined

	for(;;)
	{
		if (terminalNumber <= 0) break;
		inStream.open(inputFileName.data());			// opens the file to read from
		assert( inStream.is_open() );		
		for (;;)
		{
			inStream >> input;
		            if (input == stringTerminal) break;
			     getline(inStream, lineOfText);
			     output = lineOfText;
			   
		}
			
			 
		
			
			if( inStream.eof() ) break;
	}
		cout << "Your terminal information is:\n" << output << endl;
		cout << "Enter another terminal number 1-100 or 0 to quit:  ";
		cin >> terminalNumber;
}
	
	inStream.close();	// closes the file
	// OUTPUT
		cout << "No more terminals for you!\n"
				"Have a good day";
		cin.ignore();
		return 0;

}

sample text file called terminals.txt:

Code:

terminal1   4100 100 a 06012006
terminal2   4101 100 a 06012006
terminal3   4102 100 a 06012006
terminal4   4103 100 a 06012006
terminal5   4104 100 a 06012006
terminal99  4107 100 a 06102006

it prints out the last terminal - the "terminal 99" and loops. Any ideas?

Construct loops with actual conditions in them?
