hello im this topic:

https://www.codecademy.com/courses/learn-c-plus-plus/lessons/cpp-code-challenge-functions/exercises/cpp-functions-cc-first-three-multiples

and have this done: i now is bad but not remember how start a multiple function

```
#include <iostream>
#include <vector>
int first_three_multiples();
// Define first_three_multiples() here:
int first_three_multiples(int num){
int n=8;
for(i=0;i < n; i++){
if(n%2=0){
return = std:cout<<n;<<endl;
}
}
}
int main() {
for (int element : first_three_multiples(8)) {
std::cout << element << "\n";
}
```
