Chapter 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. You can download the class files from the blackboard ("Lab Assignments/Lab 8/Ch10_PersonType.zip")
