Still not getting it

[dgriffin66]

If I am to write a client function that computes the sum of integers in the aBag, is an array used if I do not know how many items, or what the items are?

Also, I get that the "client" is going to be the actual program. So that means the function just states what I am going to do????

if you don't know the number of items during compile time you may use a dynamic array or a standard container like vector:

http://www.cplusplus.com/reference/vector/vector/?kw=vector

vector (like most other container) has a member function size() which tells you how many items the container actually contains.

So that means the function just states what I am going to do????

I don't understand this question. Functions are what a program represents
