Well,
The only way i am going to look at this is that there are many
possible solutions to a problem, some simple and some complicated.
True. I am new to programming and am still learning. This is a good
chance for me to learn about structures,pointers, automation etc. and
relate them to my work. I would never learn to use these concepts
unless i apply them somewhere. As long as i learn something new
everyday, i'm adding something. Thats what matters. Thanks for all
your replies and suggestions. I will try them all, understand them,
and use them such that the code works.
Thanks,
Raghu
