Greeter Program in C++ Using Text File

This sample program is an class programming activity that I wrote five years ago in my programming class in C++. What does the program will do is to ask the users name and other information and then those information will be process and stored in a text file. This code will teach how to use text file using C++. I hope you will find my work useful.

Volume of a Cube in C

In this article I would like to share with you a sample program that I wrote using C as my programming language. I called this program volume of a cube in c that will ask the user to give the base, length, height of the cube and then our program will compute for it it's volume. The code is very simple I intended my work for beginners in C programming.
