Question

C++

Redo Practice program 1 from chapter 11, but this time define the Money ADT class in separate files for the interface and implementation so that the implementation can be compiled separately from any application program.

Submit three files:

• YourLastNameFirstNameInitialMoney.cpp - This file contains only the Money class implementation
• YourLastNameFirstNameInitialProj4.cpp - This file contains only the main function to use/test your money class
• YourLastNameFirstNameInitialMoney.h - This file contains the header file information.  

Optional bonus (10%): Do some research on make files. Include a make file that will compile these three files.  

This is the original practice program 11.

Answer 2

Here is the completed code for this problem. I have only splitted the code into three files namely – money.h, money.cpp and main.cpp as requested. Did not change any logic of your original program, though fixed some minor bugs. Comments are included, go through it, learn how things work and let me know if you have any doubts or if you need anything to change. If you are satisfied with the solution, please rate the answer. If not, PLEASE let me know before you rate, I’ll help you fix whatever issues. Thanks

/*OUTPUT*/

Enter an amount of money: $2.5

Your amount is $2.50

My amount is $10.09

++myAmount is $11.10

I am richer.

I have more.

Enter an amount $15.03

$15.03

$2.50 + $15.03 equals $17.53

$2.50 - $15.03 equals $-12.53
