C language is the most important subject to get a job,Most of the core/software companies asked C language in both written and interview,Because C is the basic language to learn any language coding. Here I am discussing How to prepare C language and what type of books refer to learn c language easy.
First of all you should learn basics of C from any book of your own interest and practice all example programs given in the book. The best book which I recently learnt is Let us C by Yashavant Kanetkar,which teaches from basics with simple easily understandable language.
After successful completion of  learning basics we should practice the programs in the system compiler to get full confidence on programs, Turbo-C is the basic easy compiler to compile and to check outputs of the program.To practice more in depth C programming example try to get the book exploring C by Yashavant Kanetkar, this book cover only C programs of different types.
Now download previous question papers of the companies either software or hardware,and practice those interview or written questions with different logics so,that its becomes easy to write any C program.

Professor Hawking distributed numerous books handling the key inquiries concerning the universe and our reality. Stephen wrote and published numerous logical papers and address notes.

Hawking has explained the whole universe very briefly,

He explains a lot of things related to time, dimensions, secrets of the galaxies, etc.

He put forward his views about the universe and different theories given by the great scientist of the world from ancient to the present time.

He wrote and published so many books about the universe, in each book he explains neatly about the galaxy.
Here we are trying to put best 7 Top most books written by hawkings to explain about the universe, In his books, he proved that how genius that he was.
