Product Cost Program in Rust

A program that I wrote using Rust programming language that will ask the user the cost of the product and its quantity after which it will compute its total cost. The code is very simple and intended for beginners in Rust programming.

Year Level Checker in Rust

A simple program that I wrote using Rust programming language that will ask the user what is its year level and then our program will determine whether the user is freshmen, sophomore, junior or senior. The code is very simple and easy to understand.

Circle Calculator in PHP

In this article I would like to share with you a sample program that I wrote in PHP I called this program Circle Calculator. What does the program will do is to ask the user to give the radius of the circle and then our program will compute the area and circumference of the circle. The code is very easy to understand and use. I hope you will find my work useful thank you.

Payroll Program in Turbo Pascal

In this article I would like to share with you a sample program that I wrote using Pascal as my language of choice. I called this program Payroll Program in Turbo Pascal. What does the program will do is to ask the user the name of the employee and then it will ask the number of days work. After which the program will compute the salary of the employee. I am using Turbo Pascal 6 For DOS as my compiler in writing this program.

Multiplication Table in Pascal

I there for couple of days I was not able to upload new tutorial because I don't have available internet connection at home for the moment. Anyway this article I would like to share with you how to create a multiplication table using Pascal as our programming language. I am using Turbo Pascal 6.0 for DOS as my Pascal compiler in this sample program. What does the program will do is to generate multiplication table using for loop statement in Pascal. I hope you will find my work useful. Thank you very much.
