I have an assignment and could use some help with it. I have part of it working, but not all of it.
Here is my assignment.
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:
Set the first name only.
Set the last name only.
Store and set the middle name.
Check whether a given first name is the same as the first name of this person.
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 am not sure how to get these to work.
isFirstName correctly determines if a name is a student's first name.

These ones work:
The program can initialize a personType object without error.
personType getters and setters work as expected.

I am not sure if these would work for the to fix the issue I am having. I tried adding them to the main file but they were giving me errors.
