#include<iostream>
using namespace std;

class Vehicle{
protected:
int wheel;
double weight;
public:
Vehicle(int wl,double wgt):wheel(wl),weight(wgt){
//cout<<"Vehicle()"<<endl;
}
};

class Car:virtual public Vehicle{
protected:
int passengers;
public:
Car(int wl,double wgt,int ps):passengers(ps),Vehicle(wl,wgt){
//cout<<"Car()"<<endl;
}
};

class Truck:virtual public Vehicle{
protected:
double payload;
public:
Truck(int wl,double wgt,double pl):payload(pl),Vehicle(wl,wgt){
//cout<<"Truck()"<<endl;
}
};

class Notchback:public Car,public Truck{
int flag;
public:
Notchback(int wl,double wgt,int ps,double pl,int f):flag(f),Vehicle(wl,wgt),Car(0,0,ps),Truck(0,0,pl){
if(flag==0) cout<<"Notchback constructs from Car"<<endl;
else cout<<"Notchback constructs from Truck"<<endl;
}
};

int main(){
cout<<"nb1:"<<endl;
Notchback nb1(2,3,6,2,0);
cout<<"nb2:"<<endl;
Notchback nb2(2,3,6,2,1);
}

注：
nb1为flag为0，从Car类继承
nb2为flag为非0数，从Truck类继承
