似乎是排序有问题

```cpp
if(xuesheng[i].zongchengji<xuesheng[ii].zongchengji&&xuesheng[i].id<xuesheng[ii].id)
```
你这句代码中的&&xuesheng[i].id<xuesheng[ii].id
有什么用？

swap似乎可以直接换结构体数组中的两个结构体而不用分开来写

排序出错了

排序中第一个判定中成绩小就可以直接交换了
by GuangyuHuashi @ 2022-08-11 19:59:41
else中判定也有错误
by GuangyuHuashi @ 2022-08-11 20:01:05
或者说可以去掉
by GuangyuHuashi @ 2022-08-11 20:01:42
这不用排序吧……

AC:
```cpp
#include<bits/stdc++.h>
using namespace std;
struct xuesheng
{
string mingzi;
int yuwen,shuxue,yingyu;
int zongchengji;
int id;
}xuesheng[1001];
int main()
{
int a;
cin>>a;
for(int i=0;i<a;i++)
{
cin>>xuesheng[i].mingzi;
cin>>xuesheng[i].yuwen;
cin>>xuesheng[i].shuxue;
cin>>xuesheng[i].yingyu;
xuesheng[i].id=i;
}
for(int i=0;i<a;i++)
{
xuesheng[i].zongchengji=xuesheng[i].yuwen+xuesheng[i].shuxue+xuesheng[i].yingyu;
}
for(int i=0;i<a-1;i++)
{
for(int ii=i+1;ii<a;ii++)
{
if(xuesheng[i].zongchengji<xuesheng[ii].zongchengji)
{
swap(xuesheng[i].zongchengji,xuesheng[ii].zongchengji);
swap(xuesheng[i].mingzi,xuesheng[ii].mingzi);
swap(xuesheng[i].id,xuesheng[ii].id);
swap(xuesheng[i].yuwen,xuesheng[ii].yuwen);
swap(xuesheng[i].shuxue,xuesheng[ii].shuxue);
swap(xuesheng[i].yingyu,xuesheng[ii].yingyu);
}
}
}
cout<<xuesheng[0].mingzi<<" "<<xuesheng[0].yuwen<<" "<<xuesheng[0].shuxue<<" "<<xuesheng[0].yingyu;
return 0;
}
```

@[hyc12528](/user/578809) 是不用，但尽量按楼主的思路来（个人想法）
