Data Types

Variables can store data of different types. Knowing the data type is important because you cannot, for example, add a word to a number.

Common Data Types:

Integer: Whole numbers (e.g., 5, -10).
Float/Double: Numbers with decimals (e.g., 3.14, -0.99).
String: Text characters (e.g., "Hello").
Boolean: True or False values.
Array: A collection of values.
