Explanation:
Read a number from usr and assign it to variable "num". If the input number is less than 1 or greater than 10 then ask again to enter a number until user enter a number between 1-10 only.Then with the help of switch() function print the equivalent Roman number.
Output:
Enter a number between 1 and 10: -5
Wrong input!!Enter again:12
Wrong input!!Enter again:6
The Roman numeral for 6 is:VI
