    }
  printf("\n");
}
getch();

}

-------------------

logic in mind:-
1)for this display, we have three parts.
      first part is upper 
      second part is horizontal
      third part is vertical form(look circled part)
2) First we display upper part using three loops.
          outer loop is for number of rows
           inner is for space(constant)
          inner most is for display
3) similarly, for second part we have done. ----------------------

clrscr();

    {
      printf("%c",a+j);
    }
  printf("\n");

}
getch();
}
-----------------
logic in mind
1) we have to display different characters in different rows and columns.
2)there are five rows and columns. The column is decreased in each display.
3)for this, we have used first loop for different rows.
4)second loop is for display. It fetches value from first loop and displays different character.
5)second loop is taken from value 0.because,  in each display, the character changes so.
