一般来说，Sleeping Cup 中的题目大多数需要文件读写。请在 文件IO 一栏获知文件名信息。

代码如下：

#include <bits/stdc++.h>

using namespace std;

int main()
{
   freopen("test.in", "r", stdin);
   freopen("test.out", "w", stdout);
   printf("Hello, World!");
   return 0;
}

Generally, most problems in Sleeping Cup require file I/O. Check the File IO section for filename details.

Sample code:

#include <bits/stdc++.h>

using namespace std;

int main()
{
   freopen("test.in", "r", stdin);
   freopen("test.out", "w", stdout);
   printf("Hello, World!");
   return 0;
}
