Core Concepts

1. Memory Bug Categories

Bug Type	Description	Prevention
Use-after-free	Access freed memory	Ownership, RAII
Double-free	Free same memory twice	Smart pointers
Memory leak	Never free memory	RAII, GC

Less safe                                              More safe
More control                                           Less control

// RAII: Resource Acquisition Is Initialization
// Resource lifetime tied to object lifetime

#include <memory>
#include <fstream>
#include <mutex>

// File handle with RAII
