**Question 2** 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.
