類的初始化順序實例

#include <iostream>
using namespace std;

class A{
public:
	A(int a){
		cout << a << "...." << endl;
	}
};
class B:virtual public A{
public:
	B(int a,int b,int c):aa(b),A(a){
		cout << c << "..." << endl;
	}
	virtual void func(){
		cout << "B..." << endl;
	}
private:
	A aa;
};

int main(){
	B(1,2,3);//先A，再aa，最後B;在這個基礎上只看聲明順序而非在列表中順序來初始化

	return 0;
}
