Prompt JavaScript Calculator

In this article I would like to show you how to create a prompt JavaScript calculator. Our program is very simple it will ask the user to give the first value, the second is the operator  addition, subtraction, multiplication and division and then the second value. Our program will display the result on the screen using if else statement in JavaScript.

Salary Range Checker in C++

In this article I would like to share a sample program that will demonstrate how to use if  - else if statement in C++. I also added exception handling capabilities that will only accept numbers as input values in our program using limits library in C++. I hope you will find my work useful. I am using Dev C++ in developing this program.
