MOOC清华《面向对象程序设计》第4章：继承基类构造函数实验

#include <iostream>
using namespace std;

class Base{
int data;
public:
Base(int i): data(i) {
cout << "Base::Base(" << i << ")\n" ;
}
};

class Derive:public Base{
int data{2016};
public:
using Base::Base;
void print(){
cout << "data = " << data << endl;
}
};

int main(){
Derive obj(356);
obj.print();
return 0;
}
