Storing Objects in a list

Demo Code

#include <iostream>
#include <list>
#include <string>
#include <algorithm>

using namespace std;

template<typename T>
struct printer {//w w  w . ja  v  a  2 s  . com
  void operator()(const T& s) {
    cout << s << '\n';
  }
};

bool inline even(int n) {
  return(n % 2 == 0);
}

printer<string> strPrinter;
printer<int>    intPrinter;

int main() {
  list<string> lstOne;
  list<string> lstTwo;

  lstOne.push_back("Red");
  lstOne.push_back("Green");
  lstOne.push_back("Blue");

  lstTwo.push_front("A");
  lstTwo.push_front("B");
  lstTwo.push_front("C");

  for_each(lstOne.begin(), lstOne.end(), strPrinter);

  lstOne.sort();           // list has a member for sorting
  lstTwo.sort();

  lstOne.merge(lstTwo);    // Merge the two lists and print
  for_each(lstOne.begin(), lstOne.end(), strPrinter);

  list<int> intLst;

  intLst.push_back(0);
  intLst.push_back(1);
  intLst.push_back(2);
  intLst.push_back(3);
  intLst.push_back(4);


  for_each(intLst.begin(), intLst.end(), intPrinter);

  // Or, remove all even values

  intLst.remove_if(even);
}
