我用的是devc++，没有错啊

取余符号错了

而且没有输入

判断逻辑就错了啊....

```
#include<iostream>
using namespace std;
int a;
int main(){
cin>>a;
if(a%3==0&&a%5==0&&a%7==0)
{
cout<<"3 5 7";
return 0;
}
if(a%3==0&&a%5==0)
{
cout<<"3 5";
return 0;
}
if(a%3==0&&a%7==0)
{
cout<<"3 7";
return 0;
}
if(a%5==0&&a%7==0)
{
cout<<"5 7";
return 0;
}
if(a%3==0)
{
cout<<"3";
return 0;
}
if(a%5==0)
{
cout<<"5";
return 0;
}
if(a%7==0)
{
cout<<"7";
return 0;
}
cout<<"n";
return 0;
}
```
直接给代码了

我的那个太多return有点乱
可以改成else if
by _____QWQ_____ @ 2023-11-11 11:15:42
1、改elseif
2、没有那么复杂
```c
int a;
cin>>a;
if (a%3==0){
cout<<3<<" ";
}
if (a%5==0){
cout<<5<<" ";
}
if (a%7==0){
cout<<7;
}
```
