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.

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
-
Term: Values
Definition: The actual data stored in variables or constants, such as numbers or text.
-
Term: Data Types
Definition: Specifications that categorize the nature of data that can be stored, like Integer, Float, or String.
-
Term: Variables
Definition: Named storage locations that can hold values which may change during program execution.
-
Term: Constants
Definition: Named storage locations with fixed values that do not change during program execution.
-
Term: Type Compatibility
Definition: The requirement that the value matches the data type of the variable where it is stored.
-
Term: Type Conversion
Definition: The process of converting values from one type to another, known as type casting.
