Comma Adder

In a similar fashion to my 2 previous tutorials:

http://thecodingtutorials.blogspot.com/2013/01/simple-file-manipulation-in-console.html
http://thecodingtutorials.blogspot.com/2013/01/character-arrays-in-c.html

This tutorial will show a C++ program that takes input from a file called "input.txt" and outputs it to "output.txt", only this time, it will take input like this:

1234567
1234567
1234567

and output it with commas after the third digit on each line like this:

123,4567
123,4567
123,4567

Simple File Manipulation in a Console Application with C++

The goal of this tutorial is to show you how to make a C++ console application that will read data from a file called "input.txt" that's formatted like this (with each new entry on its own line):

1234567
1234567
1234567

and output it to a file called "output.txt" that is formatted like this (standard CSV (Comma Separated Values) format, except with 25 columns per row maximum):

1234567,1234567,1234567,...(25 times)
1234567,1234567,1234567,...(25 times)
1234567,1234567,1234567,...(18 times)

Setting up and using FTP

FTP, or File Transfer Protocol, is a means of being able to transfer files from one computer to another. Usually FTP is used for transferring files to and from web servers. It is one of my favorite methods of uploading websites, scripts, files, and etc.

FTP uses a client and server program. The server program listens and waits for incoming client connections, and once a connection is established the two computers can communicate with each other and transfer files back and forth. A client program is needed to interact with the server (from a website designer/developer/manager's perspective) and upload/download files.

My favorite FTP client is FileZilla (note: FileZilla also provides a server program, but we're not going to be using that in this tutorial). It's free and it can do everything you would want to do with an FTP client - I've also never experienced any bugs or any other problems (that were not my own fault).

First, go to the FileZilla website to download the client program:
