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

class FelixClass
{
      public:
             void setName(string x)
             {
                  name = x;
              }
              string getName()
              {
                     return name;
                     }

      private:
             string name;
};

int main()
{
    FelixClass felixObject;
    felixObject.setName("Felix is best!");
    cout << felixObject.getName() << endl;
    system("pause");
    return 0;
}
