自己写了一个不错的对拍模板，分享给大家：
```cpp
#include <cstdio>
#include <cstdlib>
#include <ctime>
#include <windows.h>
using namespace std;
#define init_rand srand(time(NULL));
#define LPFILE FILE*
#define infile(name) fopen(name, "w");
#define for(x, l, r) for(int x = l; x <= r; x ++)
inline int rand(register int l, register int r) {
return rand() % (r-l+1) + l;
}
inline double rand_double() {
return (double)rand() / RAND_MAX;
}
int main()
{
init_rand
while (true)
{
LPFILE fin = infile("test.in")
int n = rand(1, 1000);
fprintf(fin, "%d\n", n);
for (i, 1, n)
fprintf(fin, "%d ", rand(1,5000));
fprintf(fin, "\n");
fclose(fin);
system("type test.in");
system("my.exe < test.in > my.out");
system("right.exe < test.in > right.out");
if (system("fc my.out right.out"))
MessageBox(NULL, "找到差异，请查看！", "找到差异", MB_OK | MB_ICONERROR),
system("pause");
}
return 0;
}
```
