@[我谔谔](/user/127284) 蟹蟹dalao但是可以给个例子吗
比如我想造P1001的10个数据

```cpp
ll chr(){return rand()&255;}
ll llrand(){ll ret=0;F(i,1,7) ret=(ret<<8)|chr();return ret;}
ll rand(ll l,ll r){return llrand()%(r-l+1)+l;}
char str[100];FILE *f;
int main()
{
F(i,1,20)
{
sprintf(str,"data%02d.in",i);f=fopen(str,"w");
int a,b;a=rand(1,1000);b=rand(1,1000);
//随机生成输入数据
fprintf(f,"%d %d\n",a,b);
//输出数据到输入文件
fclose(f);
sprintf(str,"data%02d.out",i);f=fopen(str,"w");
fprintf(f,"hahah");fclose(f);
//创建输入文件
sprintf(str,"sol.exe <xds%02d.in >xds%02d.out",i,i);
system(str);
//运行 std
}
return 0;
}
```

@[一只大头](/user/149192) freopen(s[i],"w",stdout); s[i]为"1.in","2.in","3.in",...不知道可不可以。

你自己把要输出的数据补完，然后运行一次你的文件夹中就有10组数据
数据组数改 $oo$ 变量

@[世界第一肥宅BF](/user/120074) 但是std在哪里运行啊
