Implementation of the Definition class:

void Definition::put_word(char *s)

{

   word = new char[strlen(s)+1];

   strcpy(word,s);

   nmeanings = 0;

}

void Definition::add_meaning(char *s)

{

   if (nmeanings < Maxmeans)

   {

      meanings[nmeanings] = new char[strlen(s)+1];

      strcpy(meanings[nmeanings++],s);

   }

}

char * Definition::get_meaning(int level, char *s)

{

   if (0 <= level && level < nmeanings)

      return strcpy(s,meanings[level]);

   else

      return 0;                                // line 27

}
