1) It would be better if you posted actual error messages.

2) Compare:

'Almond' : undeclared identifier
Well, you do not have class Almond anywhere, so compiler gives you an error.
Look at point 2 in my previous post again.

Furthermore: You haven't defined functions like GetCarbohydrates() and the other getters.

I think you misunderstand inheritance. class almond: public Nut implies that everything part of Nut is also part of almond. In other words: type exists twice in almond (type int Nut is just not accessible in case of the variable type almond)

Because you set your SetType() function to accept a char. And you trying to pass a string (and actually passing an int: multicharacter literal)

ok settle the things up there and now
