  12.  
  13. I have a base class, called Animal, and a derived class, called Cat.
  14.  
  15. In my main program I have:
  16.  
  17. 1.    Animal *p;
  18. 2.    Cat a(args);
  19. 3.    p = &a;
  20.  
  21. Now, if I define
  22.     class Cat:Animal{...
  23.  
  24. then I get the error in line 3:
  25.   Can not convert Cat * to Animal *
  26.  
  27. But if I define
  28.    class Cat:public Animal{...
  29.  
  30. everything is fine.
  31.  
  32. Can anyone tell me why?
  33.  
  34. Thanks,
  35.  
  36. Eric
