C++ file sorting program

[tburke]

I am having to write a program that reads in two files (file1.txt and file2.txt) and sorts them into a master file (report.txt.). File1 is NOT sorted and file2 is already sorted. Below is my code from a previous project and I plan on re-using most of it, however I need to add a sort function/array above the WHILE loop. Please let me know if you can help. I am having trouble sorting file1 by it's name. Each file contains lines of data that look like this...

"Alex Letterhead Elegant 96 2 21126
Ana Letterhead Elegant 96 1 21121
Claudette Letterhead Excalibur 40.9 1 21125
Colin Note Impression 88.5 1 21126
Earl Note Inspire 74.9 1 21123
Fred Note Imagine 62.5 1 21122
Grace Letterhead Excelsior 68.5 1 21125
Henri Letterhead Excelsior 68.5 1 21122
Hermine Note Impression 88.5 1 21124"

that is Name, type, style, price, quantity, zipcode.


#include <iostream>
#include <string>
#include <fstream>
using namespace std;



struct transaction

{os << rep.name << "\t" << rep.type << "\t" << rep.style << "\t" << rep.price << "\t" << rep.quantity;
return os;}


void main()
{
