Thanks very much for the book. I already have a couple of very good 
books by my side. Yes, I am learning C using a book, and infact I am 
reading every single line of it.

The book that I am using is Deitel & Deitel, C How to Program. I like 
the Deitel & Deitel books, they are comprehensive, up-to-date, 
standard-compliant as much as possible, and also full of tips and 
tunning tricks. They are serving me well (but they are pretty 
expensive, anyway).

Yeah, but I just learned pointers today!! That explains why the 
instructor didn't have time to teach the other functions.

yeah, I am just learning calloc, malloc, free, realloc from the man 
page.
