I fail to see what your question is.

[RRick]

You have not included any information about Animal. The compiler needs the class Animal info to compile line 10.

That should get you started.

ok so i cleared whatever i could but am stuck with 2 major errors only

plz help clear them. thanks

[nemisis]

ummmm nevermind i got it; was missing a '=' in this line in Point.h

inline Properties(Poin t mypoint=(0,0),T aste mytaste = SALTY): my_point(mypoin t), my_taste(mytast e){}

but i ll post more after i compile the whole program.

Cheers
