C Programming Tutorials and Exercises?

I'm learning C and looking for a good site with a linear set of lessons and lots of exercises to learn with. I like the tutorials here: http://www.cprogramming.com/ but it lacks exercises and sample programs to write and experiment with. Are there any sites with a modular and structured approach to teaching C with exercises?C Programming Tutorials and Exercises?
