Easily Assign Containers

STL containers overload the assignment operator, thereby allowing you to easily assign containers of the same type to one another:
  
#include <iostream> 
#include<vector>
using namespace std;

void main() 
{
 vector <int> vi;
 vi.push_back(1);
 vi.push_back(2);

 vector <int> new_vector;
 new_vector = vi;  // copy the contents of vi to new_vector; new_vector automatically grows as needed
 cout << new_vector[0] << new_vector[1] << endl;   // display 1 and 2
}
