@[yuanshanlishu](/user/679634) 函数用 `void` 类型
by TankYu @ 2023-05-23 21:25:04
@[yuanshanlishu](/user/679634) `return 0`代表返回一个数 $0$ ，就是你做完这些操作之后还会把刚返回的这个 $0$ 输出去，就是多了个 $0 $ 呗
```cpp
void answer(int k){
// 中间的一坨
return;
}
int main(){
int k;
cin>>k;
answer(k);
return 0;
}
```

@[yuanshanlishu](/user/679634)
```cpp
#include <iostream>
using namespace std;
void answer(int k)//
{
int ans = 0;//这里本身有误
int sub1, sub2, sub3;
for (int i = 10000; i <= 30000; i++)
{
sub1 = i / 100;
sub2 = i % 10000 / 10;
sub3 = i % 1000;
if ((sub1 % k == 0) && (sub2 % k == 0) && (sub3 % k == 0))
{
cout << i << endl;
ans = 1;
}
}
if (ans != 1)
{
cout << "No" << endl;
}
return;//
}
int main()
{
int k;
cin >> k;
answer(k);//
return 0;
}
```
改过的用注释标了
