@[linchenyu123](/user/1016616) 你简化干啥？

```cpp
#include<iostream>
using namespace std;
int main()
{
double a,b,c;
cin>>a>>b>>c;
cout<<(int)(a*20.0/100+b*30.0/100+c*50.0/100)<<endl;
return 0;
}
```
这样算吗（

@[linchenyu123](/user/1016616) 对呀你简化干啥干嘛，现在代码挺好的鹅。

我不信有比我更简的
我把return都删了，照样过
```
#include<iostream>
using namespace std;
int main(){
int a,b,c;
cin>>a>>b>>c;
cout<<a*0.2+b*0.3+c*0.5;
}
```

此为最简

# NO
```
#include<iostream>
int main(){
int a,b,c;
std::cin >> a >> b >> c;
std::cout << a*0.2 << b*0.3 << c*0.5}
```

## BUT..
```c
#include<bits/stdc++.h>
using namespace std;int main(){int a,b,c;cin>>a>>b>>c;cout<<a*0.2+b*0.3+c*0.5;}
```
