        scanf("%d",&b);

        printf("\nEnter third element:- ");
        scanf("%d",&c);

        if(a>b&&a>c)
        {
                  printf("%d is greater among all of them",a);
         }
   
          if(b>c&&b>a)
          {
                  printf("%d is greater among all of them",b);
           }
     
           if(c>b&&c>a)
           {
