Abstract classes (?branching)

Quidnam (1)
Hello.

I was fooling around with abstract classes (Possibly in a way you're not supposed to use them). The following code asks questions about food, and has two possible branches, Member->FruitMember and Member->NotMember, The first branch will ask questions about a fruit type of food, the second will ask general questions and output "its not a fruit!". Everything works perfectly fine, you could actually test it by replacing (see code below)
myFood = new Member;
with
1
2
 
myFood = new FruitMember2; //Or NotMember2
myFood->Info()

As you might notice, by initializing FruitMember2 we initialize all contructors that form the base of this class (Food, Member, FruitMember, FruitMember2).
The problem is, I want the program to determine which branch to take, right now its a simple check (if name of the fruit is "Apple")... Problem is, if I just declare myFood = FruitMember2, It will launch all constructors *again*, this will force the user to input the same data twice. Any ideas how to intialize only the FruitMember and FruitMember2 contructors, while preserving all data from Food and Member constructors? Seeing the code below will propably make everything clear... Thanks in advance.
