You will write a program that reads a binary file that contains records of creatures. Each record can be

stored in a Creature struct. You should present the user with a menu of three options: display a specific

creature, display

all the creatures sorted by name, or quit. If the user chooses to display a specific

creature, you should ask the user which creature to display.

You will be supplied with a starter file PA

2

_

Starter

.cpp. You will need to complete some of the code in

main a

nd write the definitions for the three functions. For sorting, you should use the sort function

found in the algorithm header file. You can read more about this function here:

http://www.cplusplus

.com/articles/NhA0RXSz/

.

Make sure you use good programming style.

Name your file PA

2

_lastName_firstName.cpp, replacing lastName with your actual last name and

firstName with your actual first name.

Submit only the cpp file.

A possible sample run will look

as follows:

Menu

1. Display a specific creature

2. Display all creatures sorted by name

3. Quit

Enter your choice (1, 2, 3):

Which creature do you want to view?
