Programming Books

I already have several books on hand that I own the cover how to program and how to use various programming languages. And that's cool.

What I'm looking for is a book that has good challenges in it for a developing programmer. Program challenges like sorting strings, doing math, using ports and memory, etc.

Can someone point me in some direction here?

I don't care about math, I care about learning how to program. I want to start programming right away, you know "hacker" style. Get a feel of the language and computer dynamics. Instead of just being some snob who practices theory all the time.

In my opinion, programming books should just be running references for syntax and function. That's all I'm really interested in right now.

What I want, however, are challenges to start waxing my skills with? Get my drift? That Euler website looks great, something for me to work on over the weekend.
