Understanding noexcept behaviour and exception safety in C++

This is a fundamental C++ question that tests whether you understand the contract and runtime semantics of the noexcept specifier. It's the kind of question interviewers ask to confirm you know not just the syntax, but what actually happens when that contract is violated.

The question probes your grasp of exception safety guarantees, the distinction between compile-time declarations and runtime behaviour, and how the standard library enforces these contracts. High-frequency trading and systems firms care about this because noexcept is often used to signal functions that must not throw under any circumstance—and knowing the consequences of violating that promise is critical to writing robust code.
