编译器说找不到类。怎么处理？请大家帮帮小弟我吧

编译器说找不到类。怎么办？请大家帮帮我吧。
因为我里面用到了友元函数，说以在VC++中用文件用#include<iostream.h> ，并把using namespace std;去掉

C/C++ code

#include<iostream.h>   #include<string>#include <iomanip>class Teacher{public:     Teacher(string nam,int Age,int Sex,char *Department,char *phone,string title1);    ~Teacher( );    void display();protected:     string name;    int m_nAge;      int m_nSex;//0:women,1:man      char *m_szDepartment;      char *m_phone;     string title;};Teacher::Teacher(string nam,int Age,int Sex,char *Department,char *phone,string title1){    name=nam;    m_nAge=Age;    m_nSex=Sex;    m_szDepartment=new char[strlen(Department)+1];  //此处的处理是个重点，处理不好，会在程序中植入非常严重且隐蔽性极强的"定时炸弹"      strcpy(m_szDepartment,Department);      m_phone=new char[strlen(phone)+1];  //此处的处理是个重点，处理不好，会在程序中植入非常严重且隐蔽性极强的"定时炸弹"      strcpy(m_phone,phone);      title=title1;    }Teacher::~Teacher()  {      delete [] m_szDepartment;      delete [] m_phone;  }  void Teacher::display(){    cout << setiosflags(ios :: left) << setw(6)  <<name<< setw(20) <<m_nAge << setw(8)<<((m_nSex==0)?"women":"man")<<setw(11)<<m_szDepartment<<setw(11)<<title1<<setw(11)<<m_phone;  }  class Cadre{public:     Cadre(string nam,int Age,int Sex,char *Department,char *phone,string post1) ;    ~Cadre( ); protected:     string name;    int m_nAge;      int m_nSex;//0:women,1:man      char *m_szDepartment;      char *m_phone;     string post;};Cadre::Cadre(string nam,int Age,int Sex,char *Department,char *phone,string post1){    name=nam;    m_nAge=Age;    m_nSex=Sex;    m_szDepartment=new char[strlen(Department)+1];  //此处的处理是个重点，处理不好，会在程序中植入非常严重且隐蔽性极强的"定时炸弹"      strcpy(m_szDepartment,Department);      m_phone=new char[strlen(phone)+1];  //此处的处理是个重点，处理不好，会在程序中植入非常严重且隐蔽性极强的"定时炸弹"      strcpy(m_phone,phone);      post=post1;}Cadre::~Cadre()  {      delete [] m_szDepartment;      delete [] m_phone;  }    class Teacher_Cadre:public Teacher,public Cadre{public:     Teacher_Cadre(string nam,int Age,int Sex,char *Department,char *phone,string title1,string post1,string wages1) ;    ~Teacher_Cadre( );     void show();    friend ostream & operator<<(ostream &,const Teacher_Cadre &);//重载运算符"<<" protected:     string name;    int m_nAge;      int m_nSex;//0:women,1:man      char *m_szDepartment;      char *m_phone;     string wages;};Teacher_Cadre::Teacher_Cadre(string nam,int Age,int Sex,char *Department,char *phone,string title1,string post1,string wages1):Teacher(nam,Age,Sex,*Department,*phone,title1),Cadre(nam,Age,Sex,*Department,*phone,post1),wages(wages1){}Teacher_Cadre::~Teacher_Cadre()  {      delete [] m_szDepartment;      delete [] m_phone;  }void Teacher_Cadre::show(){    display();}ostream & operator<<(ostream &output,const Teacher_Cadre &p)  {      output<<"工资为：";    output<<<<p.wages<<endl;      output<<"职务为：";    output<<<<p.title1<<endl;      return output;  } int main( ){    char name[10],post[19],department[10];      int sex,age;      float salary;      cout<<"input Teacher_Cadre's name,Age,sex(0:women,1:man),age,department,post,wages:\n";      cin>>name>>Age>>sex>>age>>department>>post>>wages;      Teacher_Cadre Teacher_Cadre1(name,Age,sex,age,department,post,wages);      Teacher_Cadre1.Show();     cout<<Teacher_Cadre1;    return 0;}

错误的行号是什么
[解决办法]
你看下是不是有神马中文的标点或者中文的括号，手头没有编译器。
如果你能把编译器的错误提示贴出来，我想会有更多人乐意帮你看的。。。
good luck

一堆堆的语法错误.记得仔细看错误.
main函数里面的没法改了.你自己看着改输入项

头文件少了.
#include<string>
[解决办法]
算了.
直说吧:扔掉vc6.0.
用 iostream,用 using namespace std.
[解决办法]
用vc6.0出的问题就没必要纠结了

探讨
