请问你怎么读入了 $4$ 个字符 $?$

$scanf$ 也用错了

```cpp
#include<bits/stdc++.h>
using namespace std;
int main()
{
int a[4];
scanf("%d %d %d\n",&a[1],&a[2],&a[3]);
char x,y,z;
scanf("%c%c%c",&x,&y,&z);
sort(a+1,a+4);
int ax,by,cz;
ax=x-'A'+1;
by=y-'A'+1;
cz=z-'A'+1;
printf("%d %d %d",a[ax],a[by],a[cz]);
return 0;
}
```
# 求关

@[Hhy140516](/user/1176359) 多读的那个是换行符

@[Hhy140516](/user/1176359) 您提供的代码确实AC了，但是还是不太清楚原来的为什么全WA
