Why enum works so strange? :/

[Guysl]

Another approach is using map of enumeration and string:

#include <cstdlib>
#include <iostream>
#include <map>
#include <string>


enum resolution {low,medium,hight};
std::map<resolution,std::string > resMap;


     //class
    class display{
    int width,height;
    resolution res;
    public:
    void set(int w,int h){width=w; height=h;}
    void get(int &w,int &h){w=width; h=height;}
    void setR(resolution r){res=r;}
    std::string getR(){ return resMap[res];}
         
    };

int main(int argc, char *argv[])
{
   
   resMap[low]= "low"; 
   resMap[medium]= "medium";
   resMap[hight]= "high";

    display dm[3];
    int i,w,h;
    
    dm[0].set(640,480);
    dm[1].set(800,600);
    dm[2].set(1600,1200);
    
    dm[0].setR(low);
    dm[1].setR(medium);
    dm[2].setR(hight);
    
    std::cout<<"We have:"<<std::endl;
    
    for(int i=0;i<3;i++){
    dm[i].get(w,h);
    std::cout<<dm[i].getR()<<" "<<w<<"x"<<h<<std::endl;
} 
      
    system("PAUSE");
    return 0;
}
