Question

Instructions Write a program that asks the user for a number. If the number is between 1 and 255, the program outputs the corresponding ASCII character. If it is outside of that range, the program outputs Out of range.

Answer 1

Answer:

import java.util.Scanner;

public class num5 {

   public static void main(String[] args) {

       Scanner in = new Scanner(System.in);

       System.out.println("Enter a number between 1 -255");

       int num = in.nextInt();

       if(num >= 1 && num<=255){

           char c = (char)num;

           System.out.println("The ASCII Value of "+num+" is "+c);

       }

       else{

           System.out.println("Out of range");

       }

   }

}

Explanation:

• Use the scanner class to receive a number from the user save in a variable num
• Use if statement to ensure the number is within the valid range num >= 1 && num<=255
• Convert the number to the ASCII equivalent by casting it to char data type
• Output the number and the ASCII equivalent
• if num was out of range, print Out of range
