Question

write a program to input a number.Display the product of the successors of even digits of the number entered by user by using scanner.

Answer 1

The program is written in Java language and is as follows:

import java.util.*;
public class product
{
   public static void main()
   {
       Scanner sc=new Scanner(System.in);
       int n,r,p=1;
       System.out.println("Enter a number");
       n=sc.nextInt();
       while(n!=0)
       {
         r=n%10;
         n=n/10;
          if(r%2==0)
          {
             System.out.println("\n"+"Even digit = "+r);
             System.out.println("Its successor = "+(r+1)+"\n");
              p = p * (r+1);
           }
        }
    System.out.println("\n"+"The product of successors of the digit is "+p);
  }
}   

Answer 2

Explanation:

import java.util.scanner;

{

public static void main ()

{

Scanner sc = new Scanner ( System.in);

int n,r,p=1;

System.out.print("Enter number");

n=sc.nextint();

while(n>0)

{

r=n%10;

n=n/10;

if (r%2==0)

{

p=p*(r+1)

}

}

System.out.println("Product of successors of even digits are "+p);

}

}
