The Rules of Programming Languages

Every programming language has rules, how you write it, what word exist in that language, what orders that words need to be written, or whether every instruction has to end with linebreak, semicolon, etc. These rules called syntax. You have to write the right syntax so your program working in that language.

We will examining five thing that appear in any programming language :

• Case sensitivity (Capitalization difference)
• Statements (How to write and end each instruction)
• Whitespace (What it means and why it's useful)
• Comments (Because source code isn't always obvious)
• Keywords (Which word belong to each language)
