每个数中间用一个空格隔开，不要输出换行鸭qwq

↓AC代码，在你的代码上修改了好几个点······
```
#include<iostream>
using namespace std;
int main(){
int a;
cin>>a;
if(a%3==0)
cout<<"3"<<" ";
if(a%5==0)
cout<<"5"<<" ";
if(a%7==0)
cout<<"7";
if(a%3!=0&&a%5!=0&&a%7!=0)
cout<<"n";
return 0;
}
```

@[xieyzy](/user/1048461) 要仔细看题目要求，输出没有endl······

```c++
#include<bits/stdc++.h>
using namespace std;
int main(){
int n,t;
cin>>n;
if(n%3==0)
{
cout<<"3 ";
t+=1;
}
if(n%5==0)
{
cout<<"5 ";
t+=1;
}
if(n%7==0)
{
cout<<"7";
t+=1;
}
if(t==0)
cout<<'n';
return 0;
}

我直接硬算
```cpp
#include <iostream>
using namespace std;
int main()
{
int a;
cin>>a;
if(a%7==0 && a%5==0 && a%3==0){
cout<<"3 5 7";
}else if(a%5==0 && a%3==0){
cout<<"3 5";
}else if(a%7==0 && a%3==0){
cout<<"3 7";
}else if(a%5==0 && a%7==0){
cout<<"5 7";
}else if(a%3==0){
cout<<"3";
}else if(a%5==0){
cout<<"5";
}else if(a%7==0){
cout<<"7";
}else{
cout<<"n";
}
return 0;
}
```

AC~~~~……
```
#include<bits/stdc++.h>
using namespace std;
int main(){
int a,b=0;
cin>> a;
if(a%3==0){
b=1;
cout<<"3"<<" ";
}
if(a%5==0){
b=1;
cout<<"5"<<" ";
}
if(a%7==0){
b=1;
cout<<"7";
}
if(b==0) cout<<"n";
return 0;
}
```

AC代码：
```cpp
#include<bits/stdc++.h>
using namespace std;
int main()
{
int x;//定义
cin>>x;
if (x%3==0)
cout<<"3 ";//判断是否3|
if (x%5==0)
cout<<"5 ";//5|
if (x%7==0)
cout<<"7";//7|
if (x%3!=0&&x%5!=0&&x%7!=0)
cout<<"n";//不能被357整除
return 0;
}
```
