Objectives
• To apply knowledge of classes and objects
Instructions
Implement all of the following, each in a separate Visual Studio project (and/or solution).
1. Define a class called CounterType to implement a simple counter. The class must have a private field
(data member) counter of type int. You must also provide methods (member functions), including the
following:
a. A constructor to set the counter to the value specified by the user
b. A constructor to set the counter to 0
c. A method to allow the user to set the counter to a value they specify
d. A method to increment the counter by 1
e. A method to decrement the counter by 1
Your code must ensure the value of counter is never negative. If the user calls a method to
attempt to make the counter negative, set the counter to 0 and print out an error to the user
(e.g., “The counter must not be negative.”)
Do not take any user input from inside this class. You should provide a separate main.cpp file,
housing main, in which you may test the CounterType class. You don’t need to ask for user input.
Just hardcode values for a couple different instances of CounterType to test it out.
2. Create a program to allow the user to enter a value as a Roman numeral, and store the value as a
Roman numeral (string) in a class called RomanNumeralType. You may do this through a constructor
requiring a Roman numeral to be entered
a. Provide a method to return the value as the original roman numeral
b. Provide a method to return the value as a positive integer
In your main file, in the main function, test out the following values: MCXIV, CCCLIX, and MDCLXVI
You must allow for the following symbols:
M 1000
D 500
C 100
L 50
X 10
V 5
I 1
Notes and Help:
• Our own number system (called the Hindu-Arabic number system), is a positional number system (1s
place, 10s place, 100s place, etc.) – the number positions always have meaning regardless of what the
other numbers are that surround them
• Roman numerals are an additive number system
o This means that the positions of the values depend on the values around them
• You must allow for value input of 1 to 4999 in Roman numerals
o That is, from I to MMMMCMXCIX
Counting in Roman numerals would go something like this:
I, II, III, IV, V, VI, VII, VIII, IX, X (1 – 10)
XI, XII, XIII, XIV, XV, XVI, XVII, XVIII, XIX, XX (11 – 20)
XXI, XXII, XXIII, XXIV, XXV, XXVI, XXVII, XXVIII, XXIX, XXX (21 – 30)
Pay close attention to the value 4, and the value 9 (In Roman numerals, instead of IIII, it’s “1 before 5”, which is
IV, and instead of VIIII it’s IX, which is “1 before 10”)
Other useful values that might help you:
C = 100, CC = 200, CCC = 300, CD = 400, D = 400, DC = 600, DCC = 700, DCCC = 800, CM = 900, M = 1000
Note the 400 is “100 before 500, which is 400”, and 900 is represented as “100 before 1000, which is 900”.
M = 1000, MM = 2000, MMM = 3000, MMMM = 4000
MMMMC = 4100, MMMMCC = 4200, MMMMCCC = 4300, MMMMCD = 4400, MMMMD = 4500,
MMMMDC = 4600, MMMMDCC = 4700, MMMMDCCC = 4800, MMMMCM = 4900
Note the 4900 is “4 thousands, and one hundred before the next thousand, which is 900, so it’s 4900”.
