错误信息 "use of deleted function ‘std::atomic<int>::atomic(const std::atomic<int>&)’" 表明在代码中尝试使用了 std::atomic<int> 的拷贝构造函数,但这个构造函数已经被显式删除。在C++中,std::atomic 类的拷贝构造函数和拷贝赋值运算符被删除,以防止原子类型被意外复制,从而保持其原子性。 分...

longer needed. they reduce the risk of memory leaks and dangling pointers by taking ownership of a dynamically given resource and ensuring it is properly released. examples include `std::unique_ptr`, `std::shared_ptr`, and `std::weak_ptr` in the c++ standard library. looking for a great...

Like theunique_ptr, shared_ptr is also defined in the <memory> header in the C++ Standard Library. Because it follows the concept ofshared ownership, after initializing a shared_ptr you can copy it, assign it or pass it by value in function arguments. All the instances point to the same...
