[Dev-C++] Loading variables from files [C++]

Hi,
    I am attempting to load variables from files but im not sure what 
todo because the variables are different types and sizes.
Here is the source:

#pragma once
#include <fstream>
using namespace std;

class hero
{     
     public:
          void setname(string first, string last)
          {
               fname = first;
               lname = last;
               return;
          }
           
          void setmap(int mp)
          {
               mapid = mp;
               return;
          }
         
          void setpos(int x, int y)
          {
               posx = x;
               posy = y;
               return;
          }
         
          void setmapx(int x)
          {
               posx = x;
               return;
          }
         
          void setmapy(int y)
          {
               posy = y;
               return;
          }
         
          int getmap()
          {
               return mapid;
          }

          int getmapx()
          {
               return posx;
          }

          int getmapy()
          {
               return posy;
          }    
         
          void loadinfo()
          {
               // This is where I will load the config.
          }  
         
     private:
          // Map variables.
          int mapid;
          int posx;
          int posy;
};
