In Java

Answer 1

   import java.util.Scanner;

       public class ValueOfDigits {

           public static void main(String[] args) {

               //Create new scanner

               Scanner input = new Scanner(System.in);

               //Values of each digit

               int hundreds = 0;

               int tens = 0;

               int ones = 0;

               //Prompt user to input 3 digit number            

               System.out.print("Enter a 3 digit number: ");

               int number = input.nextInt();

               //Displays hundreds place digit

               hundreds = number / 100;

               System.out.printf("Hundreds place digit: " , hundreds);

               //Displays tens digit

               tens = (number - hundreds) / 10;

               System.out.printf("\nTens place digit: " , tens);

               //Display ones digit

               ones = (number - tens - hundreds);

               System.out.printf("\nOnes place digit: " , ones);    

               //Error if number is less or more then three digits

               if (number > 999);  

               System.out.println("\nError! Number more then 3 digits.");

               if (number < 100);

               System.out.println("Error! Number less then 3 digits.");

}
