出现一个错误提示：
E:\面向对象\实验五\file03\file03.cpp(54) : error C2614: 'TeacherCader' : illegal member initialization: 'Human' is not a base or member
请问谁能帮帮忙。

我改了下。 #include<iostream>
#include<string>
using namespace std;
class Human
{
public:
    Human(string a,string b,int c)
    {
        name=a;
        sex=b;
        age=c;
    }
    void show()
    {
        cout<<"name:"<<name<<endl;
        cout<<"age:"<<age<<endl;
        cout<<"sex:"<<sex<<endl;
    }
    string name,sex;
    int age;
};
class Teacher:public Human
{
public:
    Teacher(string a,string b,int c,string d):Human(a,b,c)
    {
        title=d;
    }
    void show()
    {
        Human::show();
        cout<<"title:"<<title<<endl<<endl;
    }
public:
    string title;
};
class Cader:public Human
{
public:
    Cader(string a,string b,int c,string d):Human(a,b,c)
    {
        position=d;
    }
    void show()
    {
        Human::show();
        cout<<"position:"<<position<<endl<<endl;
    }
    string position;
};
class TeacherCader:public Teacher,public Cader
{
public:
    TeacherCader(string a,string b,int c,string d,string e):Teacher(a,b,c,d),Cader(a,b,c,e){};
    void show()
    {
        Teacher::show();
        cout<<"position:"<<position<<endl<<endl;
    }
};
int main()
{
    Teacher *aa=new Teacher("张三","男",48,"教授");
    aa->show();
    Cader *bb=new Cader("李四","男",55,"校长");
    bb->show();
    TeacherCader *cc=new TeacherCader("王五","女",45,"教授","院长");
    cc->show();
    return 0;
