Answer:
Following are the program in the C++ Programming Language.
//set header file
#include<iostream>
//set namespace
using namespace std;
//define class
class RomanNumerals
{
public:
//declare integer type variable
int number;
void getin()
{
//print message to get input
cout << "Enter a number (1 - 10): ";
//get input from the user
cin >> number;
}
void roman(){
//set switch statement
switch (number)
{ //check that the input is 1
case 1:
cout << "Roman numeral of " << number << " is: ";
cout << "I.";
break;
//check that the input is 1
case 2:
cout << "Roman numeral of " << number << " is: ";
cout << "II.";
break;
//check that the input is 1
case 3:
cout << "Roman numeral of " << number << " is: ";
cout << "III.";
break;
//check that the input is 1
case 4:
cout << "Roman numeral of " << number << " is: ";
cout << "IV.";
break;
//check that the input is 1
case 5:
cout << "Roman numeral of " << number << " is: ";
cout << "V.";
break;
//check that the input is 1
case 6:
cout << "Roman numeral of " << number << " is: ";
cout << "VI.";
break;
//check that the input is 1
case 7:
cout << "Roman numeral of " << number << " is: ";
cout << "VII.";
break;
//check that the input is 1
case 8:
cout << "Roman numeral of " << number << " is: ";
cout << "VIII.";
break;
//check that the input is 1
case 9:
cout << "Roman numeral of " << number << " is: ";
cout << "IX.";
break;
//check that the input is 1
case 10:
cout << "Roman numeral of " << number << " is: ";
cout << "X.";
break;
//if the input is other than requirement
default:
cout << "Enter number between 1 to 10.";
break;
}
}
};
//define main method
int main()
{
RomanNumerals ob;
ob.getin();
ob.roman();
return 0;
}
Output:
Enter a number (1 - 10): 9
Roman numeral of 9 is: IX.
