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 olass pornonType so that, in addition to what the existing elans 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.

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 clans. Also, write a program to test various operations on this clana.
