求大神帮忙看看这段代码的问题在哪，求修改一下

这是题目，代码如下：

#include
#include
using namespace std;

class People
{
public:
People(const string&NO,const string&name,const string&sex,const string&IDNO,const string&Birthday);
virtual void show()=0;
protected:
string name,sex,NO,IDNO,Birthday;
};

class Student:virtual public People
{
public:
Student(const string&NO,const string&name,const string&sex,const string&IDNO,const string&Birthday,int ClassNO);
void show();
protected:
int ClassNO;

};

class Teacher:virtual public People
{
public:
Teacher(const string&NO,const string&name,const string&sex,const string&IDNO,const string&Birthday,const string&principalship,const string&Department);
void show();
protected:
string principalship,Department;

};

class Graduate:virtual public Student
{
public:
Graduate(const string&NO,const string&name,const string&sex,const string&IDNO,const string&Birthday,int ClassNO,const string&Subject,const Teacher&Teacheradviser);
void show();
protected:
string Subject;
Teacher Teacheradviser;
};

class TA:public Graduate,public Teacher
{
public:
TA(const string&NO,const string&name,const string&sex,const string&IDNO,const string&Birthday,int ClassNO,const string&Subject,const Teacher&Teacheradviser,const string&principalship,const string&Department);
void show();
};

People::People(const string&NO,const string&name,const string&sex,const string&IDNO,const string&Birthday)
:NO(NO),name(name),sex(sex),IDNO(IDNO),Birthday(Birthday){}

Student::Student(const string&NO,const string&name,const string&sex,const string&IDNO,const string&Birthday,int ClassNO)

:People(name,sex,NO,IDNO,Birthday),principalship(principalship),Department(Department){}

Graduate::Graduate(const string&NO,const string&name,const string&sex,const string&IDNO,const string&Birthday,int ClassNO,const string&Subject,const Teacher&Teacheradviser)
:Student(name,sex,NO,IDNO,Birthday,ClassNO),Subject(Subject),Teacheradviser(Teacheradviser){}

TA::TA(const string&NO,const string&name,const string&sex,const string&IDNO,const string&Birthday,int ClassNO,const string&Subject,const Teacher&Teacheradviser,const string&principalship,const string&Department)
:Graduate(name,sex,NO,IDNO,Birthday,ClassNO,Subject,Teacheradviser),Teacher(name,sex,NO,IDNO,Birthday,principalship,Department){}

void Student::show()
{
cout<<" name: "<<name<<" sex: "<<sex<<" NO: "<<NO<<" IDNO: "<<IDNO<<"Birthday:"<<Birthday<<"ClassNO:"<<ClassNO<<endl;
}

void Teacher::show()
{
cout<<" name: "<<name<<" sex: "<<sex<<" NO: "<<NO<<" IDNO: "<<IDNO<<"Birthday:"<<Birthday<<"principalship:"<<principalship<<"Department:"<<Department<<endl;
}

void Graduate::show()
{
cout<<" name: "<<name<<" sex: "<<sex<<" NO: "<<NO<<" IDNO: "<<IDNO<<"Birthday:"<<Birthday<<"ClassNO:"<<ClassNO<<"Subject:"<<Subject<<"Teacheradviser:"<<Teacheradviser<<endl;
}

void TA::show()
{
cout<<" name: "<<name<<" sex: "<<sex<<" NO: "<<NO<<" IDNO: "<<IDNO<<"Birthday:"<<Birthday<<"ClassNO:"<<ClassNO<<"Subject:"<<Subject<<"Teacheradviser:"<<Teacheradviser<<"principalship:"<<principalship<<"Department:"<<Department<<endl;
}

int main()

{

Student p1("张三","男","1","532931199001150031","1990-01-15",3);
Teacher p2("李四","女","2","532931199001150041","1990-01-15","班主任","英语部");
Graduate p3("王五","男","3","532931199001150051","1990-01-15",3,"计科","李四");
TA p4("赵六","男","4","532931199001150061","1990-01-15",3,"计科","李四","助教","信息部");
p1.show();

p2.show();
p3.show();
p4.show();
return 0;

}

问题有点多：
1.构造p3和p4的时候传参不对
2.不能直接这样<<Teacheradviser，因为你没有重载过<<
3.构造函数也不对
PS:稍微帮楼主改了下
