I really do apologize but I didn't know what part of the forum to post this in, and tutorials didnt have a post new thread link. But I noticed most beginners are still trying to understand how file processing works, streaming I/O to a file, read/write etc. So I wrote a sample program for their benefit if they want to see how it works. So I truly hope this helps and again I truly am sorry if this is in the wrong area.
// Stream Write.cpp : Defines the entry point for the console application.

#include "stdafx.h"
#include <iostream>
#include <string>
#include <conio.h> // uses _getch() to pause at end of program/ program will not exit

cout << " First Name: "; cin >> fName;
cout << " Last Name: "; cin >> lName;
cout << " Middle Name: "; cin >> mName;
strcpy_s ( catenate, fName );
strcat_s ( catenate, " " );
strcat_s ( catenate, lName );

strcat_s ( catenate, mName );
cout << "\n\nYour Full Name: " << catenate << endl;
