hello aspirant,

the best book for you will be the book recommended by your college/university because, mostly the questions will come from that book by keeping it as a reference,

however some of the best books you may buy are-

1. Let Us C by Yashavant Kanetkar.
2. Data Structure Through C by Yashavant Kanetkar.
3. C in Depth by Deepali Srivastava and S. K.
4. Head First C.
5. Programming with C by Brian

hope that helps
