I can't get the following prog to compile:

...
#include <iostream.h>
#include <string.h>

class bog;

class bibliotekar {
 public:
   void nyt_fagnr(bog *, char *);
   char *skaf_fagnr(bog);
};

class bog {
 public:
   bog(char *, char *, char *);
   void vis_bog(void);
   friend char
     *bibliotekar::skaf_fagnr(bog);
   friend void
     bibliotekar::nyt_fagnr(bog *,char *);
 private:
   char titel[64];
   char forfatter[64];
   char fagnr[64];
};

bog::bog(char *titel, char *forfatter, char *fagnr)
  {
    strcopy(bog::titel, titel);
    strcopy(bog::forfatter, forfatter);
    strcopy(bog::fagnr, fagnr);
  }

void bog::vis_bog(void)
  {
    cout << "Titel: " << titel << endl;
    cout << "Forfatter: " << forfatter << endl;
    cout << "Fagnr: " << fagnr << endl;
  }

void bibliotekar::nyt_fagnr(bog *denne_bog, char *andet_fagnr)
  {
    strcopy(denne_bog->fagnr, andet_fagnr);
  }

char *bibliotekar::skaf_fagnr(bog denne_bog)
  {
    static char fagnr[64];

    strcopy(fagnr, denne_bog.fagnr);
    return(fagnr);
  }

void main(void)
  {
    bog programmering("C++", "Jamsa", "P101");
    bibliotekar bibliotek;

    programmering.vis_bog();

    bibliotek.nyt_fagnr(&programmering, "P102");

    programmering.vis_bog();
  }
EOF


It says:
In method 'bog::bog(char *, char *, char *)':
warning: implicit declaration of function 'int strcopy(...)'
undefinied reference to 'strcopy' (5 times)

I'm a total newbie, please help.
