Hi I'm very confused using references. If we use reference instead of pointer does it solve the dangling or even memory leakage problem?

(Thinking specifically of C/C++ here): a reference is just an alias, or another name for an existing object. It is usually a lot harder to create a null reference than a null pointer, so it can help solve the "dangling" problem.
Since a reference is assigned to an existing variable, it can't really contribute to a memory leak. But it is possible to have a reference to memory that has been deallocated.
