What are the key characteristics of C++ smart pointers? Select one.
- They provide exclusive and shared ownership of allocated memory.
- They provide garbage collection.
- They manage memory allocation and deallocation using a pool.
- They manage access to prevent buffer overruns.
**Explanation:**
This question asks which characteristic is a feature of C++ smart pointers. Here are the options provided, each pertaining to different memory management strategies:
1. **Exclusive and Shared Ownership**: Smart pointers in C++ can own memory exclusively or share ownership across multiple pointers, ensuring proper deallocation when there are no remaining owners.
2. **Garbage Collection**: This typically refers to automatic memory reclamation, which is not a direct feature of C++ smart pointers.
3. **Memory Pool Management**: This involves managing memory allocation and deallocation from a predefined pool, which is not a typical function of standard smart pointers.
4. **Buffer Overrun Prevention**: While smart pointers help manage memory, preventing buffer overruns is not directly within their designed functionalities.
Understanding these options is crucial for effectively managing memory in C++ programming.
