Understanding C-style casts and the four C++ cast operators

This is a medium-difficulty language-knowledge question that tests whether you understand the semantic hierarchy of C++ casting operators. Interviewers ask it to confirm that you know not just how to cast, but why C++ split casting into four distinct operators.

The question hinges on recognizing that C-style casts are a legacy feature with a specific fallback order: they attempt multiple casts in sequence until one succeeds. Understanding which of the four standard C++ casts sits outside this chain reveals important constraints about type safety and what the language designers wanted to make deliberately difficult or impossible.
