C++ 如何使用共享的\u ptr或推荐另一种方法（独特的\u ptr）
UPD:所以解决方案的要点是：如果存在复制构造函数，它将阻止移动构造函数被C++ 如何使用共享的\u ptr或推荐另一种方法（独特的\u ptr）,c++,C++,UPD:所以解决方案的要点是：如果存在复制构造函数，它将阻止移动构造函数被std:：move调用。问题已解决。 我试图根据讲师的要求编写一个“线程安全堆栈”： 它应该存储类型本身 对于基元类型，它应该通过复制接收/返回（在c中通常如此） 对于类类型，它不应该在接收/返回时调用冗余复制构造函数。使用shared_ptr实现此目的 我不能让第三个工作 更具体地说：我不知道如何向这样设计的类传递共享的ptr。而且，我几乎可以肯定我写的类本身在语法上是错误的 \ifndef安全队列 #定义安全队列 #包
