I consider my c knowledge to be above average. I can write a logic . I have written driver for several peripherals . I wish to be strong with C language . How much memory variable occupies etc . Do u guys recommend any book for me?
If you are really looking into Hardcore C coding then don't go for embedded or microcontroller oriented books, go for Operating systems or Networking based C coding books, for example
The best way to master a programming language is to go on coding,
write device drivers, linux or windows, in this case you can look at the real time output of your code.
Sorry i forgot to tell this,
the above mentioned book is a very good book which gives extensive knowledge of operating system with c code snippets on every topic mentioned and it definitely helps in mastering operating systems concepts.
