What is a variable?

In programming, a variable is like a container that holds data which can be changed while your program runs. Variables allow you to store information such as numbers, text, or other data types, so you can use them later in your code.

1.- Key Concepts #

1.1.- Declaration & Initialization #

Declaration: Tells the program you want to create a variable of a specific type.

Initialization: Assigns an initial value to the variable.

int number;         // Declaration
number = 5;         // Initialization
// Or both at once:
int anotherNumber = 10;
