Merge two lists.

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

int main()
{
  list<int> listObject1, listObject2;
  int i;

  for(i = 0; i < 10; i += 2) 
     listObject1.push_back(i);
  for(i =1; i < 11; i+=2) 
     listObject2.push_back(i);

  cout << "Contents of listObject1:\n";
  list<int>::iterator p = listObject1.begin();
  while(p != listObject1.end()) {
    cout << *p << " ";
    p++;
  }
  cout << endl << endl;

  cout << "Contents of listObject2:\n";
  p = listObject2.begin();
  while(p != listObject2.end()) {
    cout << *p << " ";
    p++;
  }
  cout << endl << endl;

  
  listObject1.merge(listObject2);
  if(listObject2.empty())
    cout << "listObject2 is now empty\n";

  cout << "Contents of listObject1 after merge:\n";
  p = listObject1.begin();
  while(p != listObject1.end()) {
    cout << *p << " ";
    p++;
  }

  return 0;
}
