In addition, accesses to atomic objects may establish inter-thread synchronization and order non-atomic memory accesses as specified by std::memory_order. The lifetime of an object must exceed the lifetime of all std::atomic_refs that references the object. While any std::atomic_ref instance...

**2. 内存管理问题** 虽然智能指针如`std::shared_ptr`和`std::unique_ptr`大大简化了内存管理,避免了很多内存泄露的问题,但不恰当的使用仍可能导致资源泄露或者循环引用,尤其是在复杂的项目如电子商务平台中。 **3. 并发编程的复杂性** 现代C++增强了对并发编程的支持,引入了`std::thread`、`std::async`...
