As the very first program or message of the software developer in the school, familiar themselves with a new programming language, every writes

"Hello, world"

Although it’s so simple program, or script, it teaches us many things behind

• How to include the library (input output module in each platform or IDE – Integrated Development Environment)
• The simple print command/instruction can be so powerful along the way, to debug or troubleshoot the program, and guide the end user.
• String – the primitive data type, very powerful and the most essential element in any program.
• How to run your first program, and excitement when you see the output displaying on your screen or mobile phone.
• It’s as the first saying to the whole programming world.

Everything starts so simple yet powerful. It proves you can do it, you can do any application, or software application as your can think of.
