老师的罚抄作业神器：
#include<iostream>
#include<fstream>
using namespace std;
int main()
{
ofstream outs;
char homework[400] ,filename[20];
long time;//长整形讽刺
cout<<"老师让你罚抄啥？:";
cin>>homework;
cout<<"老师让你抄在啥文件里？:";
cin>>filename;
cout<<"老师让你罚抄几遍？:";
cin>>time;
outs.open(filename);
for(;time>0;time--)
outs<<homework;
outs.close();
return 0;
}

用来吃饭.

只用来让键盘每个键都按一下
