What this C++ pointer dereference question tests
This is a straightforward fundamentals question on C++ pointer syntax and the relationship between pointer dereferencing and member access. It checks whether you can confidently move between different notations for the same operation—a skill that matters when reading existing codebases or writing clean code under pressure.
The question asks you to recognize that multiple syntactic forms in C++ can express the same underlying action: accessing a member function through a pointer. Understanding these equivalences deeply, rather than just memorizing them, helps you avoid bugs and read unfamiliar code quickly.

* and ->) - Member access on pointers versus references
