实验六

事先声明，我也很想用多文件写，但是！！我就不明白了，为什么我一用多文件我的电脑就会崩掉

造成不便请谅解

第一题

#include<iostream>
using namespace std;
class add{
	public:
		add(int m0,int n0):m(m0),n(n0){cout<<m+n<<endl;}
			private:
				int m,n;
};
class A: virtual public add{
	public:
		A(int m0,int n0):add(m0,n0),m1(m0),n1(n0){};
		void sub()
		{
			cout<<m1-n1<<endl;
	}
		private:
			int m1,n1;
};
class B: virtual public add{
	public:
		B(int m0,int n0):add(m0,n0),m2(m0),n2(n0){};
		void mul()
		{
		
			cout<<m2*n2<<endl;
	}
		private:
			int m2,n2;
};
class C :virtual public add{
	public:
		C(int m0,int n0):add(m0,n0),m3(m0),n3(n0){};
		void div()
		{
		
			cout<<m3/n3<<endl;
	}
		private:
			int m3,n3;
};
int main()
{	cout<<"芯片A"<<endl;
	A a(2,1);
	a.sub();
	cout<<"芯片B"<<endl;
