Which term means names for data that changes in a program?

• A. Variables
• B. Constants
• C. Data types
• D. Char

Answer: (A)

Names for data that can change in a program are called variables. A variable is a labeled storage location you can assign a value to and later update with a different value as the program runs. This ability to hold and modify different values over time is what makes them the right term for data that changes. Constants, on the other hand, hold values that don’t change once set. Data types describe what kind of data is stored (like integers, floating-point numbers, or characters) rather than whether the value can change, and Char is a specific data type for a single character, not the general idea of changing data.
