c++ using a member function to place one object inside another

[Volapiik]

So I have two classes UnsortedType and Appoinment.

Appointment accepts user input as "1/23/1999 Coffee" which would result in 1 as the month 23 as the day and 1999 as the year along with Coffee as the description.

UnsortedType just stores a list of these Appoinment objects.

In main after storing user input into an appoinment object, I want to add it to the list via method PutItem. I do this as shown below(part of main.cpp):

{
    cout << "Add the date and description of your appointment:";
    cin >> a; //storing user input in Appointment a
    x.PutItem(a); //attempting to store Appointment A in UnsortedType x
}

However, this does not seem to work as it says class "Appoinment" has no member "PutItem"

Any ideas on fix, or on how I can accomplish my goal?

Any ideas on fix

You could write a member function called PutItem for class Appointment.

[Volapiik]

my assignment requires PutItem to be a part of UnsortedType.
Also I don't understand the error message since I am using the member function using the object x which is UnsortedType so there shouldn't be an issue.

[Volapiik]

for anyone curious the solution was I accidentally had the x object initialized as both Appointment and UnsortedType in main. Solution is to remove Appointment x.
