Sum and Average of Numbers Using Array in Java

A simple program that I wrote in Java to find the sum and average of numbers using one dimensional array in Java. What the program does it will ask the user to give a series of integer number and then the program will compute the sum and average of the five numbers given by the user of our program.

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.
