Write a program that converts a number entered in Roman numerals to a positive integer. Your program
int previous - 1008;
should consist of a class, say romanType. The class roman'Type consists of:
for (i - e i« length, i++) {
switch (romantNun [i]) {
case 'M": sum - 1000;
1. Two private member variables: romanNum(type string) and num(type int) to store an
;
integer in roman format and decimal format.
2. Four functions:
if (previous < 1000)

a. setRoman which take a string as parameter and assign it to the member
'roamNum'. This function is a void function.
b. roman'ToPositiveInteger () which takes no parameter and converts the
carresponding roman string|called 'romanNum) to the private member 'num'. this
function is a vaid function.
C. printPositiveInteger which prints out the values from num with proper
labels. This function is a void const function.
d. printRoman which prints out the values from roamNum with proper labels. This

a. A default constructor without parameter. This constructor set romanNum to "I"
(roman numeral one) and num to 1(number ane);
b. A constructor with one parameter of string type. This constructor sets the
romanNum to the string passed in as the parameter and calls
romaToPositiveInteger to convert the romanNum to the corresponding
decimal integer and store it to num.
