Void Pointer Dereferencing

What this C++ void-pointer dereferencing question tests

This is an easy question on C++ language fundamentals, specifically how the compiler and runtime handle pointer types and dereferencing. It checks whether you understand the rules around void pointers and what operations are—and are not—legal on them.

Void pointers are a powerful but error-prone feature in C++. Candidates need to know when dereferencing is allowed, what the compiler will do (or refuse to do), and why void pointers require explicit casting before use in most contexts. This question rewards precision over guesswork.
