 To be specific, you will need to:
 
-1. Implement a destructor for the `User` class. To do so, implement the `User::~User()` SMF.
-2. Make the `User` class copy constructible. To do so, implement the `User::User(const User& user)` SMF.
-3. Make the `User` class copy assignable. To do so, implement the `User& User::operator=(const User& user)` SMF.
-4. Prevent the `User` class from being move constructed. To do so, delete the `User::User(User&& user)` SMF. 
-5. Prevent the `User` class from being move assigned. To do so, delete the `User& User::operator=(User&& user)` SMF.

 In performing these tasks, you are expected to make changes to **both** the `user.h` and `user.cpp` files.

+The function signature for this operator should be `User& operator+=(const User& rhs)`. Note that like the copy-assignment operator, it returns a reference to itself.

 ### `operator<`
 
 Recall that the `<` operator is required to store users in a `std::set`, as `std::set` is implemented in terms of the comparison operator. Implement `operator<` to compare users alphabetically by name. For example:
