In C++, the “struct” is known as a structure that is a special function member within a struct. The “struct” constructor is used to initialize its member variables and enable users to make a new group of variables consisting of mixed data types in a single place. In simple words, th...

联合里面的东西共享内存,所以静态、引用都不能用,因为他们不可能共享内存。 不是所有类都能作为union的成员变量,如果一个类,包括其父类,含有自定义的constructor,copy constructor,destructor,copy assignment operator(拷贝赋值运算符), virtual function中的任意一个, 那么这种类型的变量不能作为union的成员变量,因为他...
