Question 1

What is the difference between a pointer and a reference in C++?

Accepted Answer

A pointer stores a memory address and can be reassigned or null; a reference is an alias for an existing variable that must be initialized and can never be reseated.

Question 2

What is RAII, and why is it central to idiomatic C++?

Accepted Answer

RAII ties a resource's lifetime to an object's lifetime, acquiring it in the constructor and releasing it in the destructor, giving deterministic and exception-safe cleanup.
