C++ || Class – Roman Numeral To Integer & Integer To Roman Numeral Conversion

April 10, 2012 admin No comments

The following is another homework assignment which was presented in a C++ Data Structures course. This program was assigned in order to practice the use of the class data structure, which is very similar to the struct data structure.

REQUIRED KNOWLEDGE FOR THIS PROGRAM

Header Files - How To Use Them Class - What Is It? Do/While Loop Passing a Value By Reference Roman Numerals - How Do You Convert To Decimal? Online Roman Numeral Converter - Check For Correct Results

This is an interactive program in which the user has the option of selecting from 7 modes of operation. Of those modes, the user has the option of entering in roman numerals for conversion, entering in decimal numbers for conversion, displaying the recently entered number, and finally converting between roman or decimal values.

A sample of the menu is as followed:
(Where the user would enter numbers 1-7 to select a choice)





		
		
			From the following menu:

1.  Enter a Decimal number
2.  Enter a Roman Numeral
3.  Convert from Decimal to Roman
4.  Convert from Roman to Decimal
5.  Print the current Decimal number
6.  Print the current Roman Numeral
7.  Quit

Please enter a selection:

						From the following menu:
 
1.  Enter a Decimal number
2.  Enter a Roman Numeral
3.  Convert from Decimal to Roman
4.  Convert from Roman to Decimal
5.  Print the current Decimal number
6.  Print the current Roman Numeral
7.  Quit
 
Please enter a selection:

This program was implemented into 3 different files (two .cpp files, and one header file .h). So the code for this program will be broken up into 3 sections, the main file (.cpp), the header file (.h), and the implementation of the functions within the header file (.cpp).

======== FILE #1 – Menu.cpp ========

NOTE: On some compilers, you may have to add #include < cstdlib> in order for the code to compile.
