多重继承 二义性 问题

C/C++ code

#include<iostream>#include <string>using namespace std;class Teacher{public:    Teacher(string na): name(na){}protected:    string name;};class Cadre{public:    Cadre(string na): name(na){}protected:    string name;};class Teacher_Cadre: public Teacher,public Cadre{public:    Teacher_Cadre(string na,double w):      Teacher(name),Cadre(name)      {          wages=w;      }      void show();private:    double wages;};void Teacher_Cadre::show(){    cout<<"name="<<Teacher::name<<endl;    /*cout<<"age="<<age<<endl;    cout<<"sex="<<sex<<endl;    cout<<"address="<<address<<endl;    cout<<"callnum="<<callnum<<endl;    cout<<"title="<<title<<endl;    cout<<"wages="<<wages<<endl;*/    }int main(){    Teacher_Cadre t1("li",5000.0);    t1.show();    return 0;    }

错误1error C2385: ambiguous access of 'name'


书上只说了 调用show函数会出现二义性 ，可以 初始化现在也出现了 应该怎么解决？

[解决办法]
那个书上，构造函数也是象你这么写的吗？
什么书呀？
[解决办法]

C/C++ code

Teacher_Cadre(string na,double w):      Teacher(name),Cadre(name)

输出结果：

class test1 data:       2
class testbase from test2
class testbase data:    3
class testbase from test1
class testbase data:    1

destruct class test3
desturct class test2
destruct class testbase
desturct class test1
destruct class testbase
给你个例子看看吧
