C++

The name of the file must be convertermain.cpp

As a software programmer in a financial institution, you have been asked to develop a program that converts dollar amounts between $0 and $9,999 from numbers to words. The program will only accept whole numbers. For instance, it takes $815 and converts it into eight hundred fifteen.

Design a class called Converter to be used in this program. The class should have one integer member variable; int value, and a static array of string objects that specifies how to convert dollar amounts into the desired format. For example:

The Converter class will include a constructor that accepts a nonnegative integer to initialize the Converter object. The class will also include a member function display() that displays the word description of the Converter object. The class will be used in a main function that asks the user to enter a number within the specified range and then displays the word description.

* Your code should be structured into the following files:

- Converter.cpp

- Converter.h

- convertermain.cpp

- makefile
