Factorial of a Number Using Functions in Python

Write a program that will ask the user to give a number and then the program will compute its factorial value of the given number and display the result on the screen. The program also asks the user if the user will continue using the program or not. If the user chooses Y for yes the program will run again but if the user chooses N for no the program will display a thankful message and return to the operating system.

Login System Using Visual Basic 6 and MySQL

In this article, I would like to share with you the work of my friend, fellow software engineer and business partner Mr. Larry Dave Lacapag Emol he is a Visual Basic 6 Developer who wrote many applications in Visual Basic for 8 years already. You can also visit his website which contains many free source code in Visual Basic 6 free to download at the following web address https://davesterz.blogspot.com/

This program is a login system that has a backend database MySQL the code is very easy to follow and understand feel free to use in your own programming project.

Applications of C Programming Language

The C programming language developed by Dr. Dennis M. Ritchie in 1972 has many applications below is the list of its applications.

Applications of C Programming Language

Through the years of its existence in the software development world. The C programming language is being used to create a wide range of software application. Some of the applications of C language is given below.

The C programming language is primarily being used in the development of embedded software’s that are being used in mobile phones, microwave oven, washing machines and smart television for example.

The C language was being used developed popular database management systems like Oracle Database, MySQL, Dbase, CA-Clipper, FoxBASE, Microsoft FoxPro, SQLite, and PostgreSQL.

Operating systems like UNIX and Linux is written entirely in C language.

The creation and the development of computer games like Quake II and Doom is written entirely in C language.
Statistical software and programming languages like R and numerical analysis software like MATLAB, Freemat and GNU Octave are written in C.
Scripting programming languages like PHP, Perl, bash, csh, HTML, Javascript, make and tcl are all written in C.

Image editing software like GIMP (GNU Image Manipulation Program) and darktable are written entirely in C programming language.
Text editor software like Vim, vi, Metapad, Geany, and Emacs are written in C programming language.
