C ++类多重继承错误

Question

I have been working on multiple inheritance. I have made a program but it keeps giving me an error such as Human::getInfo is ambiguous. How do I solve the problem here is my code

#include <iostream>
#include <string>
using namespace std;

class Man{
protected:
    std::string name;
public:
    void getInfo(string hName){
        name = hName;
    }
    void showInfo(){
        std::cout << "Your name is: " << name << std::endl;
        std::cout << "And you are a MAN" << std::endl;
    }
};

class Women:public Man{
public:
    Women(){}
    void Women_showInfo(){
        std::cout << "Your name is: " << name << std::endl;
        std::cout << "And you are a Women" << std::endl;
    }
};

class Human:public Women, public Man{
public:
    Human(){}
};
int main(){
    //local variables
    string choice;
    string name;
    //class object
    Human person;
    //user interface
    cout << "What your name: " ;
    cin >> name;
    cout << "Are you a [boy/girl]: ";
    cin >> choice;
    //saving name 
    person.getInfo(name); //ambiguous
    //if handler
    if (choice == "boy"){
        person.showInfo(); //ambiguous 
    }else if(choice == "girl"){
        person.Women_showInfo(); //works fine no error
    }
    system("pause");
    return 0;
}

Also feel free to make changes in my code and would be even better if your could point out my mistake using my code.

Answer 1

Your design is rather questionable, but the particular ambiguity arises because Human inherits from both Woman and Man , but Woman already inherits from Man .

So Human has two getinfo() functions in it - Human::Man::getinfo() and Human::Woman::Man::getinfo() . Unless you tell the compiler which one to use it doesn't know, and thus reports an error.
