Have Some Q's About HW. Code included.

Beginner159 (10)
My C++ teacher gave me some part of the code because many of us were stuck.

Here was the assigned project.
Example 10- 10 defined a class personType to store the name of a person. The member functions that we included merely print the name and set the name of a person. Redefine the class personType so that, in addition to what the existing class does, you can:
a. Set the first name only.
b. Set the last name only.
c. Store and set the middle name.
d. Check whether a given first name is the same as the first name of this person.
e. Check whether a given last name is the same as the last name of this person. Write the definitions of the member functions to implement the operations for this class. Also, write a program to test various operations on this class.

I think I have a b and c down.
D and E are my main problems.

If you could maybe show me some better ways to code.
OR if you could show me how to fix my project so I know how to do it in the future.
Thank you.

All you need to do is check whether any given name is equal to the person of interest.

If you already know who you are going to be comparing to, just have the user input the name, an pass that name and the name of the person of interest, compare with "==". If they are the same, the function returns true, if not, it returns false.
