  System.out.print("Enter the number of terms: ");
  int n = sc.nextInt();
  int s = 0, c;                                          // s for terms of series, c for n terms
  for (c = 1; c <= n; c++)                          // To generate n terms
  {
   s = s * 10 + 1;
   System.out.print(s + " ");
  }                                                           //for  ends

    Every step will be same. Except
    for (c=n; c>=1; c--)
    {
    s = s / 10; // / will give only the quotient so if n = 11111 s will be 1111.
    S.o.p(s + " ");
    }

    It's not printing the in that output format. I want that if n =5 then the output must be like:-
    1,11,111,1111,11111.
    A comma and a full stop must also be printed. Pls help.

      s = s * 10 + 1;
      System.out.print(s + " ");

      Change the last line to
      s = s * 10 + 1;
      System.out.print(s + " , ");
