books title for c data structures exercises

Hi all, I'm a computer science student, I've opened this thread to ask you a title of book/ebook/site/etc where I can find exercises solved of C data structures.
At my Algorithms course we use as textbook "Alghorithms in C" by Robert Sedgewick, it's a good book, but in addition of this book I'm looking for an exercises book or everything else, with solved exercises with trees, heaps, lists, graphs etc where I can exercise me.
Searching the web I've not founded a lot, do you have some advice?
Thanks in advance and sorry for my English.

I do not see anything critical wrong with your english ;)

A perfect book for me on algorithms is the one of Cormen. It has many exercises.Some of them are pretty tough!The solutions are nod provided in the book, but when i want to see how one is solved i search the net and because this book is taught in many universities there are many pdf's containing solutions for it.

Even without the solutions, i would certainly suggest it to you :)

PS - i have the greek one, so i do not know the title of the english version.Mine says : Introduction to algorithms

first of all thank you for the answer :),
I've given a look to the contents, it seems a lot theoretical, what I'm looking for is a book or everything for the lab part, the implementation in C of the Data Structures with exercises with them, example "write a function that takes in input a binary tree and..." or "write a function that calculate the maximum element in a stack" etc just to make you an idea :).

You are more than welcome.

Only K&R book comes to my mind.This is the best reference for C , but again might be not what you are looking for. Or navathe's book but this one focuses on databases.

All the books i know as an answer to your question are written in Greek. :/

Advice : Ask your professor by writing an email..Sure he is going to appreciate that ;)
