ANSWER
Answered 2020-Apr-18 at 15:16You are using C++, not Python. In C++, a variable of object type is the object; it doesn't "reference" anything. fst and snd are separate variables and therefore are separate objects. The only valid comparison is to ask the value of their objects if they are equivalent.
Variables of reference type don't provide the operation you're looking for either. A reference variable is intended to act (as much as practical) exactly like the object it references. References are commonly said to be a different name for the same object. So asking the question if two reference variables reference the same object is considered irrelevant in C++.
If you need to make this distinction between "referencing the same object" and "objects with the same value" (and you rarely do), then you need to use the C++ mechanism that provides that distinction: pointers. There, you can check for pointer equivalence (and thus "references the same object") or dereference the pointers and check for object equivalence.
