The function is called strcpy().
The following changes
66,67d
61d

53c
int main(void)
.
48,49c
strcpy(fagnr, denne_bog.fagnr);
.
42c
strcpy(denne_bog->fagnr, andet_fagnr);
.
28,30c
strcpy(bog::titel, titel);
strcpy(bog::forfatter, forfatter);
strcpy(bog::fagnr, fagnr);
.

produce the following:
#include <iostream.h>

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