Variables and data types are fundamental concepts in computer programming and data management. They form the building blocks for storing, manipulating, and organizing data within a program. Here's a brief overview of these concepts:

Variables:

Definition: A variable is a symbolic name or identifier that represents a memory location where data can be stored and manipulated.
Purpose: Variables are used to store and manage information in a program. They act as placeholders for values that can change during the execution of the program.
Declaration: Before using a variable, it needs to be declared by specifying its name and data type. For example, in many programming languages, you might declare a variable like this: int age; (declaring an integer variable named "age").
Data Types:

Definition: Data types define the nature of the data that a variable can hold. They specify the size and format of the values that can be stored in a variable.
Common Data Types:
Integer (int): Represents whole numbers without any decimal points.
Float/Double: Represents numbers with decimal points.
Character (char): Represents a single character, like a letter or a symbol.
String: Represents a sequence of characters.
Boolean (bool): Represents true or false values.
