`printf ("%d.2lf",a[0]);`

%d.2lf？
by fvv3183 @ 2020-08-12 08:52:52
```cpp
sort (a+n,a);
```
这里似乎也有问题？从没有见过这么写的。。
```cpp
bool cmp(int a,int b){
return a>b;
}
...
sort(a,a+n,cmp);
```

不好意思，写错了，cmp的参数是double类型

将
```cpp
sort (a+n,a);
```
改成
```cpp
sort (a,a+n);
```
将
```cpp
printf ("%d.2lf",a[0]);
```
改成
```cpp
printf ("%.2lf",a[0]);
```
