5. 默认移动构造函数(Default Move Constructor):将一个对象的资源(如堆内存)从一个对象转移到另一个对象。6. 默认移动赋值运算符(Default Move Assignment Operator):将一个对象的资源(如堆内存)从一个对象转移到另一个已经存在的对象。 =default关键字只能用于特殊成员函数(Special Member Functions),也就是上述...

Because we defined the destructor, we must define the copy and move operations. The = default is the best and simplest way of doing that. 因为定义了析构函数,我们必须定义拷贝和移动操作。使用=default是达到相同效果的最好、最简单的方式。
