// C++ program to demonstrate how vectors
// can be passed by reference.
#include <bits/stdc++.h>
using namespace std;
  
// The vect is passed by reference and changes
// made here reflect in main()
void func(vector<int>& vect) { vect.push_back(30); }
  
int main()
{
    vector<int> vect;
    vect.push_back(10);
    vect.push_back(20);
  
    func(vect);
  
    for (int i = 0; i < vect.size(); i++)
        cout << vect[i] << " ";
  
    return 0;
}
