1. make_unique 同 unique_ptr 、auto_ptr 等一样,都是 smart pointer,可以取代new 并且无需 delete pointer,有助于代码管理。 2. make_unique 创建并返回 unique_ptr 至指定类型的对象,这一点从其构造函数能看出来。make_unique相较于unique_ptr 则更加安全。 3. 编译器不同,make_unique 要求更新(Visual ...
首先,确保你的代码中包含了<memory>头文件,该头文件提供了智能指针的相关功能。 定义一个基类类型的指针,例如BaseClass* ptr。 使用std::make_shared函数创建一个基类类型的智能指针,将指针作为参数传递给该函数。例如,使用以下代码创建一个名为sharedPtr的智能指针: ...
