The code for DateType.h, DateType.cpp, User.h, and User.cpp and located below instructions

Implement SortedUserType as a class sorted user objects. Create and implement the specification file (SortedUserType.h) and implementation file (SortedUserType.cpp). The SortedUserType class uses NodeUser struct to create a node of a user in the list. For testing purposes, SortedUserType can store a maximum of 5 users (maxList). The user object will be inserted based on the increasing order of the users dateOfBirth.

(Struct) Implement NodeUser struct in the SortedUserType.h and SortedUserType.cpp.

NodeUser has two fields:

User userInfo; // data info

NodeUser* next; // pointer

(SortedUserType operations) the SortedUserType class has the following operation:

Normal operators:

• (Constructor) SortedUserType ();
• (Transformer) void ResetList();
• (Transformer) void MakeEmpty();// delete all item in the list
• (Observer) bool IsFull() const;
• (Observer) int GetLength() const;

Pointer related operators:

• (Observer) User* GetUser(User* aUser, bool& found) const; // get a user from the list whose firstName, lastName, and dateOfBirth match with aUser.
• (Transformer) void PutUser(User* aUser); // put aUser in to the list according to dateOfBirth order.
• (Transformer) void DeleteUser(User* aUser); // delete a user from the list whose firstName, lastName, and dateOfBirth match with aUser.
• (Observer) User* GetNextUser(); // get the next user in the list
