C++类互相引用的问题，跪求高手回答，困扰已久

class student;
class teacher
{
public:
void setname( string a ) { name = a; }
string getname() { return name; }
//void liststudentsname()
//{
//for(int i=0; i<students.size(); i++) cout<<students[i]->getname(); 
//}
//void add(student s) { students.push_back(&student); }
private:
string name;
vector<student*> students;
};
class student
{
public:
string getname() { return name; }
string getteachername() { return myteacher->getname(); }
void setname( string a ) { name = a; }
void setteacher(teacher *t) { myteacher = t; }
private:
int age;
string name;
teacher* myteacher;
};

注释部分编译会遇到错误！
我不想把teacher* myteacher和vector<student*> students放在public（我知道放在public中很容易实现），也不想通过定义两个.h文件用一个include另一个。急求答案！ c++

简单的把你的commentted out的部分分开成声明和定义？

在你的header file底端做类似

void teacher::add(student s)
{
students.push_back(&s);
}

另外，楼主注意这个函数的潜在问题

私有成员，通过它的成员方法调用
[解决办法]
class student;
class teacher
{
public:
friend class student;
void setname( string a ) { name = a; }
string getname() { return name; }
void liststudentsname();

void add(student *s) { students.push_back(s); }
private:
string name;
vector<student*> students;
};

class student
{

public:
friend class teacher;
string getname() { return name; }
string getteachername() { return myteacher->getname(); }
void setname( string a ) { name = a; }
void setteacher(teacher *t) { myteacher = t; }
private:
int age;
string name;
teacher* myteacher;
};

void teacher::liststudentsname()
{
for(int i=0; i<students.size(); i++)
cout<<students[i]->getname();
}

我也不太清楚为什么inline就不行

所以就直接在类外定义了
[解决办法]
注释部分调用了student的memfun，解决办法是在另一个文件写函数实现，另外
函数应该为：

void add(student* s) { students.push_back(student); }

[解决办法]

#include <iostream>
#include <vector>
#include <string>

using namespace std;

class student;

class teacher
{
public:
void setname( string a ) { name = a; }
string getname() { return name; }
void liststudentsname();
void add(student& s);
private:
string name;
vector<student*> students;
};

class student
{
public:
string getname() { return name; }
string getteachername() { return myteacher->getname(); }
void setname( string a ) { name = a; }
void setteacher(teacher *t) { myteacher = t; }
private:
int age;
string name;
teacher* myteacher;
};

void teacher::liststudentsname()
{
for(int i=0; i<students.size(); i++)
cout<<students[i]->getname();
}
void teacher::add(student& s)
{
students.push_back(&s);
}
