ASCII—American Standard Code for Information Interchange
Answer:
The solution code is written in Java
- import java.util.Scanner;
-
- public class Main {
- public static void main (String [] args) {
-
- Scanner inStream = new Scanner(System.in);
- System.out.print("Please input a number (1 - 10): ");
- int num = inStream.nextInt();
-
- if(num < 1 || num > 10){
- System.out.println("The input must be between 1 - 10");
- }else{
- switch(num){
- case 1:
- System.out.println("I");
- break;
- case 2:
- System.out.println("II");
- break;
- case 3:
- System.out.println("III");
- break;
- case 4:
- System.out.println("IV");
- break;
- case 5:
- System.out.println("V");
- break;
- case 6:
- System.out.println("VI");
- break;
- case 7:
- System.out.println("VII");
- break;
- case 8:
- System.out.println("VIII");
- break;
- case 9:
- System.out.println("IX");
- break;
- case 10:
- System.out.println("X");
- break;
- }
- }
- }
- }
Explanation:
The first part of this program (Line 6 - 8) is to get input number from user using Scanner object. Input validation has been done to check if the input number is in the acceptable range (Line 10). If not, an error message will be displayed (Line 11).
If the input number is in the range of 1 - 10, the number will go through a series of switch statements checking. If the number meet the condition in one of the switch cases, it will print the corresponding roman numeral specified in the case block (Line 13 - 44). For example, if input number is 9, the case 9 condition is met and "IX" will be printed.
