根据上个帖子,更正了1和5：

#include<iostream>
#include<windows.h>
#define maxn 1000000
#define maxm 1000
using namespace std;
int main()
{
    cout<<"电脑病毒\n";
    Sleep(1000);
    cout<<"就是病毒haha\n";
    Sleep(1000);
    cout<<"你有1/5的概率存活";
    Sleep(1000);
    system("cls");
    while(1)
    {
    	cout<<"输入一个数字(1-5):\n";
    	int a;cin>>a;
    	if(a==1)
    	{
    		cout<<"你好像很想摸鱼";
			while(1)
    	    	system("start https://digdig.io/");
		}
		else if(a==2)
		{
			cout<<"you are surive!!!(真的吗)";
			Sleep(1000);
			cout<<"但是,你的电脑想休息了";
			Sleep(100);
			system("shutdown /s /t 3");
		}
		else if(a==3)
		{
			cout<<"弹窗已出现";
			while(1) system("start cmd");
		}
		else if(a==4)
		{
			cout<<"你竟然活了下来!!!";
			Sleep(1000);
			return 0;
		}
		else if(a==5)
		{
            cout<<"鼠标叛变事件！！！";
			while(1)SetCursorPos(rand()%1000,rand()%1000);
		}
	}
}
