Understanding “Variables” in Programming — A Mailbox Analogy for Coding Beginners | Funifytools

1. A variable is like a mailbox that stores data — you can open it, check its contents, or replace them anytime.

2. It gives a name to a reserved memory space, making programs easier for humans to read and manage.

3. Programming is about storing, updating, and reusing values, and variables make this process possible.

4. The value inside a variable can change, but its name stays the same, helping track logic flow.

5. Understanding variables helps you easily learn conditions, loops, and functions, as they all rely on this concept.
