memory-safety-patterns

To prevent use-after-free and memory leaks in C++, use RAII principles and smart pointers like unique_ptr and shared_ptr to tie resource management to object lifetimes, ensuring automatic deallocation and nullifying dangling pointers.

Preventing data races in Rust requires using ownership rules and thread-safe constructs like atomics, mutexes, and RwLocks, which the language enforces at compile time to ensure safe concurrent memory access.

RAII provides memory safety by binding resource lifecycles to object scope, automatically releasing memory and preventing leaks and double-free errors when objects go out of scope in languages like C++, Rust, and C.

Use weak_ptr instead of shared_ptr to break circular reference cycles and prevent memory leaks, observing memory without claiming ownership, while shared_ptr is for shared ownership where the last owner deallocates the resource.

Implementing bounds checking for buffer overflows in C requires manual validation of array and vector indices during access, as the language lacks built-in safety spectrums and automatic bounds enforcement found in higher-level constructs.

Rust ownership enforces memory safety at compile time via strict borrowing rules, while C++ smart pointers offer flexibility but rely on developer discipline; choose Rust for guaranteed safety or C++ for gradual integration into existing systems.
