I need the codes for extRomanType.cpp, extRomanType.h, main.cpp, romanType.cpp, romanType.h
// I will definitely rate and give thumbs up.
Here are the initial codes, this might help in building the program.
main.cpp

cout << "Num1 = " << num1 << endl;
cout << "Num2 = " << num2 << endl;
cout << "Num1 + Num2 = " << num1+num2 << endl;
cout << "Num1 * Num2 = " << num1*num2 << endl;
cout << "Num1 - Num2 = " << num1 - num2 << endl;

Instructions
In programming Exercise 6 in Chapter 10, we defined a class romanType to implement Roman
numbers in a program. In that exercise, we also implemented a function,
romanToPositiveInteger , to convert a Roman number into its equivalent positive integer.
Modify the definition of the class romanType so that the member variables are declared as
protected . Furthermore, overload the stream insertion and stream extraction operators for easy
input and output. The stream insertion operator outputs the Roman number in the Roman format.
Also, include a member function, positiveIntegerToRoman , that converts a positive integer to
an equivalent Roman number format. Write the definition of the member function
positiveIntegerToRoman
For simplicity, we assume that only the letter I can appear in front of another letter and that it
appears only in front of the letters V and X. For example, 4 is represented as IV, 9 is represented as
IX, 39 is represented as XXXIX, and 49 is represented as XXXXIX. Also, 40 willI be represented as
XXXX, 190 will be represented as CLXXXX, and so on.

Transcribed Image Text: Extending the romanType class
Instructions
Derive a class extRomanType from the class romanType to do the following: In the class
extRomanType , overload the arithmetic operators +, - , * , and / so that arithmetic
operations can be performed on Roman numbers. Also, overload the pre- and post-increment and
decrement operators as member functions of the class extRomanType .
To add (subtract, multiply, or divide) Roman numbers, add (subtract, multiply, or divide,
respectively) their positive integer representations and then convert the result to the Roman
number format. For subtraction, if the first number is smaller than the second number, output a
message saying that, "Because the first number is smaller than the second, the numbers
cannot be subtracted". Similarly, for division, the numerator must be larger than the denominator.
Use similar conventions for the increment and decrement operators.
Write a main() to test your class.
