A copy assignment operator is implemented by the compiler automatically unless you provide one.
拷贝赋值运算符是由编译器自动实现,除非你提供一个。
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。

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。
