Odd and Even Number Checker in Rust

Hello friends in this article I would like to share with you how to write a program to check if the given number by the user is odd or even number  using Rust Programming language. Yesterday I am attending a lecture in Mozilla Philippines office here in Makati City, Philippines. The talk is given by Sir Bob Reyes a Mozilla representative here in the Philippines he is discussing the Rust programming language I found his lecture interesting because Rust is designed for systems programming and best of all it is open source.

Rust is a programming language that is developed by Mozilla foundation the creator of Mozilla Firefox web browser one of the most popular and secure web browser in the world. I hope you will give a try to learn Rust.

In this program it will ask the user to give a number and then our program will determine whether the given number is odd and even.

Addition of Five Numbers in AngularJS

In this article I would like to share with you a sample program that I wrote using AngularJS one of the most popular javascript framework today. What does the program will do is to ask the user to give five numbers and then it will find the sum of the five numbers that is being provided by the user. What is good about this program is that it uses buttons to add the sum of numbers and clear button to clear the content of the text box. I hope you will find my work useful.

Currency Converter in C++

In this article I would like to share with you a sample program that I wrote 6 years ago in my class in C++ programming I called this program currency converter in C++. I will ask the user amount of money in US dollars and then it will convert into Philippine Peso equivalent using structure as my data structure in C++. I hope you will find my work useful in learning C++ programming.

Compare Two Strings in Java

In this article I would like to share with you a sample program that I wrote in Java to compare the two string if they are the same or the first string is greater than the second string or vice versa. One of the things that I love in Java is that there are many built in functions that makes programming much easier compared to other programming language. I hope you will find my work useful.
