Accessing an array of structs from a class

slappy5star (4)
In the function buy drink I want to associate a user choice (entered in main) with an item name in DrinkInfo drinks[].

I tried this:

 
 
cout << drinks[choice].name;


This is not working. What is the proper way to access this array?

Thank you!
