Variables, Data Types, and Variable Naming
In programming, a variable is a container that stores a value. The value can be a number, a string of text, a boolean (true or false), or another type of data.
Data types specify the type of data a variable can hold. They ensure that programs are compatible and work correctly.
Here are the four most common data types:
Integer: A whole number (e.g., 1, 2, -3)
Float: A decimal number (e.g., 3.14, -1.5)
String: A sequence of characters (e.g., "Hello, world!", "Python")
Boolean: True or False
There are also other data types available depending on the programming language you're using.
