In C++ Write a program that converts a number entered in Roman numerals to decimal. Your program should consist of a class, say,romanType. An object of typeromanTypeshould do the following:a. Store the number as a Romannumeral.b. Convert and store the number into decimalform.c. Print the number as a Roman numeral ordecimal number as requested by the user.The decimal values of the Roman numerals are:M 1000D 500C 100L 50X 10V 5I 1d. Test your program using the followingRoman numerals: MCXIV, CCCLIX,...
Write the roman.cpp implementation file that converts a number entered in Roman numerals to a positive integer. Your program should consist of a class, say, romanType. An object of type romanType should do the following: Step a: Store the number as a Roman numeral. Step b: Convert and store the number as a positive integer. Step c: Print the number as a Roman numeral or positive integer as requested by the user. Step d: Test your program using the following...
*MUST BE IN C PROGRAMMING* Demonstrate the ability to think critically Demonstrate the ability to work with strings and chars Demonstrate the ability to design a menu system Write a simple program that allows the user to enter a number between 1 and 1000. The program will then display the Roman numeral equivalent. Allow the user to keep entering numbers for conversion to Roman numerals, or to quit, using a menu system of your own design. Submission Requirements: You are to write...
3. (a) Outline any four features of Object-Oriented Programming OOP, giving examples in each case. [16 marks] (b) Consider the following code fragments: If a = 10; Evaluate the new value of “b” in the following: (i) b = ++ a; (ii) b = a ++; What value would a and b store in (i) and (ii) after program execution? [4 marks] 4. Create a C++ program that makes use of three arrays; name, mark, grade. The program should accept...
Assignment Draw a flowchart, using Microsoft Visio or LucidChart, to document the logic required to complete this program Save the flowchart as a PDF file Develop a C++ program, following the logic in your flowchart, to convert a series of whole number decimal values to their Roman equivalent. Develop a function that will accept a whole number value in the range 1-9999 and return a string containing the long-form Roman Numeral equivalent of the input value, consisting only of upper-case...
