Token in C

The littlest significant unit in C programing language is called Token.

Tokens are like Building Blocks:

Imagine you're building a castle with colorful Lego blocks. In C language, your program is like that castle, and tokens are the Lego blocks. Each token has a special meaning, and you use them to create the whole structure of your program.

Types of Tokens:

Keywords:

Keywords are like the special Lego pieces with predefined shapes. In C, words like int, float, if, and while are keywords. They have specific jobs, like declaring variables or making decisions in your program.

Identifiers:

Identifiers are like naming your Lego creations. They can be words you make up, like age or height. These names help you remember what different parts of your program do.

Constants:

Constants are like unchanging Lego pieces. In C, you might have a constant like 5 or 3.14. They are values that don't change while your program is running.

Strings:

Strings are like chains of Lego pieces. In C, you use double quotes to make a string, like "Hello, World!". It's a way to group a bunch of characters together.

Operators:

Operators are like tools to manipulate your Lego pieces. In C, you have symbols like +, -, *, and / that help you add, subtract, multiply, and divide.

Punctuation:

Punctuation is like the separators between your Lego sections. In C, things like commas ,, semicolons ;, and parentheses () help organize and structure your code.

Comments:

Comments are like little notes to yourself. You use // for a comment that goes on one line or /* */ for a comment that can span multiple lines. These notes help you remember what your code is doing.

Putting it All Together:

Now, imagine you're building your Lego castle, and you use different Lego pieces (tokens) to create towers (functions), walls (statements), and doors (decisions). Each piece has a job, and together they make your castle (program) stand strong!

So, in C language, tokens are like the building blocks that you use to construct your program. They each have a role, and when you combine them in the right way, you create something amazing!.
