The Memory Model's Introduction

What this C++ memory model history question tests

This is a straightforward easy-level knowledge question about a foundational shift in C++ language design. It checks whether you understand when the standard introduced formal guarantees around how threads interact with shared memory — a critical piece of background for anyone writing concurrent code.

Quant trading firms rely on candidates to know this era of the language, since modern high-performance systems depend on memory ordering, atomic operations, and synchronization primitives that all stem from this standardisation effort. The question rewards direct familiarity with C++ standards history rather than problem-solving skill.
