Which term describes a program that is easy to fix and change?

• A. Meaningful identifiers
• B. Compiler
• C. Input command
• D. Maintainable program

Answer: (D)

Maintenance of code is about how easily you can fix bugs, update features, or adapt the program to new requirements without causing new problems. When code is well-structured, uses clear, descriptive names, is modular, and documented, changes can be localized to small parts of the program. That makes the software easy to maintain. The option about meaningful identifiers helps readability, but by itself it doesn’t guarantee the ease of making changes. A compiler is just the tool that turns code into executable, not about how easy it is to modify the code. An input command is simply a way to read data, not related to how maintainable the program is. So the best term for describing something easy to fix and change is a maintainable program.
