I found K&R C to be refreshingly easy to follow, but that isn't saying much because prior to that I had learned C++ from Stroustrup's book (which I had to read three times cover-to-cover before I finally understood what in the world he was talking about). Any book would seem easy to follow after that pan-galactic gargle blaster.

And now I'm sure someone will respond saying that they found Stroustrup's book remarkably straightforward. To each his own I suppose.
