This article explores the core differences between automatic and dynamic memory allocation in C++ programming, explaining why automatic storage should be prioritized. By comparing stack and heap memory management mechanisms, it illustrates how the RAII (Resource Acquisition Is Initialization) principle uses destructors to automatically manage resources and prevent memory leaks. Through concrete code examples, the article demonstrates how standard library classes like std::string encapsulate dynamic memory, eliminating the need for direct new/delete usage. It also discusses valid scenarios for dynamic allocation, such as unknown memory size at runtime or data persistence across scopes. Finally, using a Line class example, it shows how improper dynamic allocation can lead to double-free issues, emphasizing the composability and scalability advantages of automatic storage.
