7. Values and Types
Values are the actual data stored in variables, while types define their nature, impacting how they are manipulated in programming. Understanding both concepts is essential for writing efficient and error-free code. Different data types ensure correctness in operations and prevent conversion errors during program execution.

7.2What Are Values?
Values represent the actual data in programming, such as numbers and text.
What we have learnt
- Values are the actual data stored in variables and constants.
- Data types categorize the nature of the data, including Integer, Float, Character, String, and Boolean.
- Variables can change values, while constants remain fixed.
Key Concepts
- -- Values
- The actual data stored in variables or constants, such as numbers or text.
- -- Data Types
- Specifications that categorize the nature of data that can be stored, like Integer, Float, or String.
- -- Variables
- Named storage locations that can hold values which may change during program execution.
- -- Constants
- Named storage locations with fixed values that do not change during program execution.
- -- Type Compatibility
- The requirement that the value matches the data type of the variable where it is stored.
- -- Type Conversion
- The process of converting values from one type to another, known as type casting.
