Why is automatic memory management, characteristic of some languages, not available in C++?

In C++, automatic memory management is absent because the language is originally oriented towards high performance and resource control. C++ provides the programmer with direct access to memory management (allocation and deallocation), which allows optimizing resource usage but requires careful handling.

Automatic management, as in languages with garbage collectors (e.g., Java or C#), adds overhead and reduces predictability, which is unacceptable for system programming where speed and control are critical.

Instead, C++ uses smart pointers (e.g., std::unique_ptr, std::shared_ptr) to help automate memory management while still giving the programmer control over object lifetime.
