Which term denotes a named storage location whose value can change during program execution?

• A. String
• B. URL
• C. Variable
• D. Programming Language

Answer: (C)

Think of a named container in a program that you can store a value in and later replace with a new value during execution. That container is called a variable. It is exactly a named storage location in memory whose contents can change as the program runs, which is what “value can change during program execution” describes. A string is a type for text, not the storage mechanism itself; a URL is just a kind of text value (often stored as a string); a programming language is the tool used to write the program, not a storage location. So the best fit for the description is variable.
