In low-latency trading, struct memory layout is critical for performance, as poor alignment causes CPU cache misses that degrade sub-microsecond data processing. Quant developers use compiler intrinsics like offsetof and sizeof to audit and optimize data structures for maximum efficiency. This ensures that data received from a network feed matches the in-memory layout expected by high-performance code. Task Implement the function inspect_market_tick_layout() which takes no arguments. It must re
