Write a program in Objective C, take a number in a method as an argument and print the digits of a number in Word form. Using interface and implementation. E.g.123 output one two three

#import <Foundation/Foundation.h>

@interface digits:NSObject

{

    int rev,n,n1,d;

   

}

-(void)reverse;

@end

@implementation digits

-(void)reverse

{

    printf("Enter any Numeric Value:");

    scanf("%d",&n);

   

    while (n!=0)

    {

        d=n%10;

        rev=rev*10+d;

        n=n/10;

    }

   

    while (rev!=0)

    {

        d=rev%10;

        switch (d)

        {

            case 0:

                printf("Zero\n");

                break;

               

            case 1:

                printf("One\n");

                break;

               

            case 2:

                break;

               

            case 3:

                printf("Three\n");

                break;

               

            case 4:

                printf("Four\n");

                break;

               

            case 5:

                printf("Five\n");

                break;
