c++, 多继承

一个类继承自多个父类，且父类都有相同的函数，子类会调用那个父类的函数呢？

code

#include <iostream>
using namespace std;

//基类
class BaseA{
public:
    BaseA(int a, int b);
    ~BaseA();
    void show()
    {
        cout << "in baseA" << endl;
    }
protected:
    int m_a;
    int m_b;
};
BaseA::BaseA(int a, int b): m_a(a), m_b(b){
    cout<<"BaseA constructor"<<endl;
}
BaseA::~BaseA(){
    cout<<"BaseA destructor"<<endl;
}

//基类
class BaseB{
public:
    BaseB(int c, int d);
    ~BaseB();
protected:
    int m_c;
    int m_d;
};
BaseB::BaseB(int c, int d): m_c(c), m_d(d){
    cout<<"BaseB constructor"<<endl;
}
BaseB::~BaseB(){
    cout<<"BaseB destructor"<<endl;
}

//派生类
class Derived: public BaseA, public BaseB{
public:
    Derived(int a, int b, int c, int d, int e);
    ~Derived();

    void show()
    {
        cout << "in baseB " << endl;
    }

private:
    int m_e;
};
Derived::Derived(int a, int b, int c, int d, int e): BaseA(a, b), BaseB(c, d), m_e(e){
    cout<<"Derived constructor"<<endl;
}
Derived::~Derived(){
    cout<<"Derived destructor"<<endl;
}


int main(){
    Derived obj(1, 2, 3, 4, 5);
    obj.show();
    return 0;
}

输出

BaseA constructor
BaseB constructor
Derived constructor
in baseB
Derived destructor
BaseB destructor
BaseA destructor

应该是会调用最后继承的父类的函数
