cpp-pointer-safety-management

What problem does it solve?

Pointer misuse in C/C++ can lead to memory leaks, memory corruption, and dangling pointers. This skill provides guidelines to declare, initialize, manage, and release pointers safely to reduce these risks.

Core Features & Use Cases

• Explicit type specification with the "asterisk rule": declare pointers with explicit types and place the asterisk next to the pointer name for readability.
• Immediate initialization and safe memory handling: initialize pointers upon declaration and assign valid memory or nullptr; never leave uninitialized.
• Pre-use validation and modern techniques: validate pointers before dereferencing, use smart pointers (RAII) where possible, and encapsulate pointer operations to minimize risk.
• Common pitfalls and safety practices: avoid dereferencing null, prevent memory leaks, and ensure proper cleanup to maintain program stability.
• Real-world scenarios: safe pointer usage during dynamic memory allocation, API design, and legacy code refactoring.

Quick Start

Apply these pointer-safety guidelines to a sample module and verify safe behavior through compilation and runtime checks.
