In this program, you will use string manipulation to create a new $"$spy name" given a first and last name.

The user is prompted to type a first and last name as input, with a space between them. Your program must be able to account for first names and last names of up to $19$ characters each.

To generate the name, the program will:

Subtract the length $($number of characters$)$ of the first name from the length of the last name to get an "increment amount," which may be positive or negative. Example: there are five letters in "James" and four letters in "Bond", so the increment amount is $4-5=-1$

Update both the first and last name by incrementing all characters in the name by the amount determined in the previous step. The exception is lowercase letters from the phrase "exam three"; so$,$ the letters $"$a$","$e$","$h$","$m$","$t$"$ and $"$x$"$ will remain unchanged.

Swap the updated first name with the updated last name

In addition to completing the main$()$ function, there are two functions you must complete the definitions for:

incString: given a string variable and an increment amount, updates the string by adding the increment amount to all characters except the letters listed above.

getSwappedFullName: given a first and last name in separate string variables, fills a third string variable with the swapped names and a space between them

Below is a sample run of the program:

Type your first and last name: Thorin Oakenshield

First name: Thorin

Last name: Oakenshield

Updating both names by $5...$

Updated first name: Yhtwns

Updated last name: Tapesxhneqi

Your new spy name is Tapesxhneqi Yhtwns

To get full credit, you must pass the unit tests by filling in the function definitions as specified, not just printing the expected output in main$()$

You will find this lab much easier if you use the functions available in the string.h library.

You do not need to account for any user errors, nor for the cases where characters fall outside the range of a$-$z$.$
