Which feature allows C++ functions to return a reference to an object?

Dynamic allocation
Pointer arithmetic
Reference return values
Class inheritance

The correct answer is: Reference return values

Reference return values allow C++ functions to return a reference to an object. This is used instead of returning the object itself or a pointer to it, as it reduces the risk of memory leaks and can make the code more readable. Dynamic allocation (A) refers to creating new objects dynamically at runtime, and is not directly related to returning references. Pointer arithmetic (B) deals with manipulating pointers rather than return values. Class inheritance (D) allows for the creation of hierarchical relationships between classes, but does not directly relate to return values. Therefore, these other options are incorrect.
