Write a program that asks the user to enter a number within the range of 1 through 10. Use a switch statement to display the Roman numeral version of that number. Do not accept a number less than 1 or greater than 10. The output of the program should be just a Roman numeral, such as VII. Your program class should be called RomanNumerals

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.

Explanation:

Following are the description of the program.
