Left of '.getDrinkPrice' must have class/struct/union - c++

Question

This is a project from a c++ book I'm learning from.
I keep getting the error
"left of '.getDrinkPrice' must have class/struct/union"
I have tried fixing it but I just keep messing it up further. The visual studio error lists aren't too friendly for new users and this is really bothering me. I obviously don't want the code to be reposted fixed but I do want to be pointed in the right direction.

Answer 1

*Cola->getDrinkName is not correct.
Use either Cola->getDrinkName() or (*Cola).getDrinkName() instead; same for all other calls of the same kind in your code.
