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