C++对象构造问题

#include<iostream>
using namespace std;
class Base1{
public:
	Base1(){
		cout<<"Base1()"<<endl;
	}
	Base1(int a):base1a(a){ 
		cout<<"Base1(int)"<<endl;
	}
private:
	int base1a;
};

class Base2{
public:
	Base2(){
	cout<<"Base2()"<<endl;
	}
	Base2(int b):base2a(b){
	cout<<"Base2(int)"<<endl;
	}
private:
	int base2a;
};

class Derived:public Base1,public Base2{
public:
	Derived(int a,int b):Base1(a),Base2(b),base1(a),base2(b){}
private:
	Base1 base1;
	Base2 base2;
};
int main(){

	Derived d(2,3);
}

输出结果：

Base1(int)
Base2(int)
Base1(int)
Base2(int)
请按任意键继续. . .

输出结果分析：

Base1 和Base2的默认构造函数不运行
