What term describes a memory location in a program that can change during execution?

• A. Variable
• B. Constant
• C. Array
• D. Pointer

Answer: (A)

A variable is a storage location in a program whose value can change during execution. You declare it to hold data and then update it as the program runs, like assigning a new value to it or modifying it through operations. For example, initializing an integer variable with 0 and then incrementing it shows how the same memory location can hold different values over time. A constant is a value that doesn’t change once set. An array is a collection of multiple values, not a single memory location that changes. A pointer stores an address, and while that address can change if you assign a new one, the standard term for a memory location whose content can change is a variable.
