没有插入代码，告辞

您输出那边是不是没有乘号，或者试试看在输出的时候强转实数类型
比如
```
printf("%.0f",a*0.2+b*0.3+c*0.5);
```

@[CSJ1](/space/show?uid=87026) 写了乘号，发现问题在*0.2这类上，改成*2/10就好了

@[Esport_P1ayErX](/space/show?uid=73552) ```cpp
#include<bits/stdc++.h>
using namespace std;
int a,b,c;
int main()
{
scanf("%d %d %d",&a,&b,&c);
printf("%d",a*0.2+b*0.3+c*0.5);
return 0;
}
```
啊大佬我的错

```cpp
#include<bits/stdc++.h>
using namespace std;
int a,b,c;
int main()
{
scanf("%d %d %d",&a,&b,&c);
printf("%d",a*0.2+b*0.3+c*0.5);
return 0;
}
```

```c
#include<bits/stdc++.h>
using namespace std;
int main()
{
int a,b,c,sum;
scanf("%d %d %d",&a,&b,&c);
sum=a*0.2+b*0.3+c*0.5;
printf("%d",sum);
return 0;
}
```
真的不能再继续了吗

@[隋正昊](/space/show?uid=37556) 不能赋值给sum的,赋值NOIP只能得60分或30分
by 谦谦君子 @ 2018-08-08 18:42:19
```cpp
#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;
return 0;
}
```
这样写没毛病
