哪出问题了呢

编译过吗?错误提示很详细的呀

两处拼写错误

Quote:

Student(string nam,char sex,int a,float sco):Person(nam,s,a),scoer(sco){}

Copy code

Student(string nam,char s,int a,float sco):Person(nam,s,a),score(sco){}

Teacher及Student的构造函数参数个数错误,Person类无默认构造函数

Quote:

Teacher(nam,a,t),Student(nam,s,sco),wage(w){}

Copy code

Person(nam,s,a),Teacher(nam,s,a,t),Student(nam,s,a,sco),wage(w){}

改后的全部代码

Copy code

#include<iostream>
#include<string>
using namespace std;
class Person
{public:
Person(string nam,char s,int a)
{name=nam;
sex=s;
age=a;
}
protected:
    string name;
    char sex;
    int age;
};
class Teacher:virtual public Person
{public:
Teacher(string nam,char s,int a,string t):Person(nam,s,a),title(t){}
protected:
    string title;
};
class Student:virtual public Person
{public:
Student(string nam,char s,int a,float sco):Person(nam,s,a),score(sco){}
protected:
    float score;
};
class Graduate:public Teacher,public Student
{public:
Graduate(string nam,int a,char s,string t,float sco,float w):
Person(nam,s,a),Teacher(nam,s,a,t),Student(nam,s,a,sco),wage(w){}
void show()
{cout<<"name:"<<name<<endl;
cout<<"age:"<<age<<endl;
cout<<"sex:"<<sex<<endl;
cout<<"score:"<<score<<endl;
cout<<"title:"<<title<<endl;
cout<<"wages:"<<wage<<endl;
}
private:
    float wage;
};
int main()
{Graduate grad1("Wang-li",24,'f',"assistant",89.5,1234.5);
grad1.show();
return 0;
}
