If a class defines a copy constructor, acopy assignment operator, or a destructor, then it should define all three.
假定一个类界讲了拷贝机闭函数、赋值操纵符、析构函数中的一个，那么一样平常需供齐数界讲那仨函数。
Now, try using a copy construction and operator assignment for class a, declared in Listing 15.
现在，尝试为类a使用一个复制结构和运算符赋值，在清单15中声明该类。
Well, the assignment operator makes a copy of the thing on the right and puts it in the thing on the left.
赋值操作符把右边的东西，复制到左边。
Each class whose instance will go into the container must implement at least the copy constructor it is good to implement also the assignment operator.
每个类(其实例要在容器内使用)必须至少实现拷贝构造函数(实现赋值运算符，也是好习惯)。
To manage a class with pointer members, we must define all three copy-control members: the copy constructor, assignment operator, and the destructor.
为了管理具有指针成员的类，必须定义三个复制控制成员：复制构造函数、赋值操作符和析构函数。
To resolve C2299, do not make the copy constructor or assignment operator a template function, but rather a non-template function that takes a class type.
若要解决C2299，请不要使复制构造函数或赋值运算符成为模板函数，而使其成为采用类类型的非模板函数。
When I return by value from an assignment operator, firstly what is the mechanism and basis of calling the copy constructor?
当我返回值赋值操作符，首先是调用复制构造函数为基础的机制？
The assignment operator is applied on a initialized object, but this is not the case in the copy constructor.
赋值运算符是应用于一个初始化的对象，但这并不是拷贝构造函数的情况下。
The assignment operator is applied on a initialized object, but this is not the case in the copy constructor.
