// C++ code to demonstrate the working of assign()
  
#include <iostream>
#include <list> // for list operations
using namespace std;
  
int main() 
{
    // declaring list
    list<int> list1;
    list<int> list2;
    list<int> list3;
      
    // initializing array
    int arr[10] = { 1, 2, 3, 4 };
      
    // using assign() to insert multiple numbers
    // creates 4 occurrences of "2"
    list1.assign(4,2);
      
    // Printing the assigned list
    cout << "The list after inserting multiple elements is : ";
    for (list<int>::iterator i=list1.begin(); i!=list1.end(); i++)
       cout << *i << " ";
      
    cout << endl;
      
    // using assign() to copy elements of list to other
    // assigns 4 occurrences of "2"
    list2.assign(list1.begin(),list1.end());

       cout << *i << " ";
      
    cout << endl;
      
    // using assign() to copy elements of array to list
    // assigns array elements
    list3.assign(arr,arr+4);
