Memory-safe programming patterns for RAII, ownership, smart pointers, and resource management across Rust, C++, and C.

• Covers six core memory bug categories (use-after-free, double-free, leaks, buffer overflow, dangling pointers, data races) with language-specific prevention strategies
• Provides RAII patterns in C++ with destructors, lock guards, and transactions; smart pointer guidance (unique_ptr, shared_ptr, weak_ptr) with custom deleters
• Implements Rust ownership, borrowing, lifetimes, and interior mutability (Cell, RefCell, Rc, Arc) with compile-time safety guarantees
• Includes safe C patterns using goto cleanup, opaque pointers with create/destroy pairs, and GCC cleanup attributes
• Demonstrates bounds checking via containers and spans in C++, and iterators in Rust; thread-safe patterns using atomics, mutexes, and RwLock across languages
