What term describes a memory location whose value cannot be changed after initialization?

• A. Variables
• B. Constants
• C. Arrays
• D. Pointers

Answer: (B)

Value stability after initialization is the key idea here. A constant describes a memory location whose value cannot be changed after initialization. Declaring a constant protects values that must remain fixed, such as mathematical constants or configuration limits, with the language enforcing against reassignments. A variable is meant to be mutable, a memory location whose content can change. An array is a collection of elements, and a pointer stores a memory address rather than a direct value. Declaring a constant ensures attempts to modify that value are rejected, keeping the data unchanged throughout the program.
