Student Tuition Fee Solver in PHP

A simple program that I wrote in PHP in my web programming class in college I called this program Student Tuition Fee Solver in PHP that will compute the payment of the student based on the course and units being enrolled by the student in school.

Feel free to use my code in your programming projects at school or work. If you have some questions please send me an email at jakerpomperada@gmail.com and jakerpomperada@yahoo.com.

People here in the Philippines can reach me at my mobile number 09173084360.

Thank you very much and Happy Programming.

Student Grading System in PHP and MySQL

Most of my career as programmer spend developing programs using PHP and MySQL. In this article I would like to share my program that I wrote a long time ago I called this program Student Grading System in PHP and MySQL. This program will compute and store the grades of the student in MySQL.

Feel free to use my code in your programming projects at school or work. If you have some questions please send me an email at jakerpomperada@gmail.com and jakerpomperada@yahoo.com.

People here in the Philippines can reach me at my mobile number 09173084360.

Thank you very much and Happy Programming.

Least Common Multiple (LCM) Solver in Java

This sample program that I wrote in Java programming language will ask the user to enter two numbers and then our program will compute and determine the least common multiple or LCM of the two numbers being provided by our user.

Feel free to use my code in your programming projects at school or work. If you have some questions please send me an email at jakerpomperada@gmail.com and jakerpomperada@yahoo.com.

People here in the Philippines can reach me at my mobile number 09173084360.

Thank you very much and Happy Programming.
