{
strcpy(Academician::speciality,speciality);
}
virtualvoid outmembers(ostream &out)
{
out<<"Age："<
protected:
char speciality[80];
};
class GraduateStudent:public Academician
{
public:
GraduateStudent(int age = 0,char *name = "\0",char *speciality="\0",
char *investigate="\0"):Academician(age,name,speciality)
{
strcpy(GraduateStudent::investigate,investigate);
}
virtualvoid outmembers(ostream &out)
{
out<<"Age："<
protected:
char investigate[100];
};
intmain()
{
Academician a(24,"管宁","Computer Science");
cout<
cout<
}
在上面的代码中为了能够区分输出a对象与b对象，我们用虚函数的方式重载了继承类Academician与多重继承类GraduateStudent的outmembers成员函数，由于ostream& operator <<(ostream& out,Student &temp) 运算符重载函数是Student基类的，Student &temp参数通过虚函数的定义可以适应不同派生类对象，所以在其内部调用temp.outmembers(out); 系统可识别不同继类的outmembers()成员函数。
最后看一下，右移运算符的重载，右移运算符我们也常叫它输入运算符号，对于它来说，具体实现和左移运算符的重载差别并不大，对于有多成员对象的类来说，只要保证能够完整输入各成员对象大数据就可以了。
