Suggest books and sites to find interesting problems to solve

[hotshot05]

Can you suggest some websites and books in which various interesting problems and puzzles are given(only problem statement will do)?

I found one link : 10 Puzzle Websites to Sharpen Your Programming Skills

Do you know of any more sites?

And the above post does not give the name of any book.

So if you know the name of any books with puzzles (in C), please suggest

The C Puzzle Book by Alan R Feuer is a great book. It doen't contain any theory , just puzzles & solutions. It's not an intro book, you need to know the basics well.
