Addition of Three Numbers in Pascal

I wrote this program to ask the user to give three numbers and then the program will compute the sum of three numbers using Pascal as my programming language.

Sum of Three Numbers in Pascal

In this article I would like to share with you a sample program that I wrote using Pascal as my programming language that will ask the user to give three numbers and then our program will compute the total sum of three numbers using functions in Pascal. The compiler that I am using in this sample program is Turbo Pascal For Windows. The code is very simple and easy to understand.
