#include <iostream>
#include <vector>
using namespace std;

int main()
{
// Establish variables
int SomeElement;
vector<int> num;

cout << "Pick 5 non-zero numbers" << endl;
// Take in all the values
while(cin >> SomeElement){
  num.push_back(SomeElement);
}

cout << "Your numbers are: ";
// Reply all the values
for(int i = 0; i < num.size(); i++){
  cout << num[i];
  if(i != num.size()-1){
    cout << ", ";
  }
}

return 0;
