// Define first_three_multiples() here:

There’s a problem with how you declared the function, and where you declared the vector.

@byte7264334216

#include <iostream>
#include <vector>

// Define first_three_multiples() here:
int first_three_multiples(int num){
  std::vector multiples;
  multiples.push_back(num * 1);
  multiples.push_back(num * 2);
  multiples.push_back(num * 3);
  return multiples;
}

int main() {

  for (int element : first_three_multiples(8)) {
    std::cout << element << "\n";
  }

}

The beginning of the first_three_multiples function should be

std::vector<int> first_three_multiples(int num){
  std::vector<int> multiples;

because you are trying to return a vector of ints, not a single int.
And the type inside the vector would be declared here using <int> .
