ambiguity resolution in multiple inheritance

problem arises sometimes while dealing with multiple inheritance 

for e.g

sometimes when a derived class which is inherited from  multiple base classes which have a method

with same name and return type but derived has no such method of its own 

in this case when we try to call that function/method using derived class object it causes ambiguity 

because it confuses the compiler between the method definitions and choosing which one to call 

in that case we use a scope resoluion operator along with class name and method to be called 

its shown in the following code

 #include <iostream>

using namespace std;

class A

{

public:

    void show()

    {

        cout << "hi\n";

    }

};

class b

{

public:

    void show()

    {

        cout << "hi from b\n";

    }

};

class c : public A, public b

{

    public:

    void show() { A::show(); }

};

int main()

{

   

    c ce;

    ce.show();

    return 0;

}
