More C Code

The publicity from Wired and Slashdot has yielded more searches for C and C++ topics than ever before and I noticed there were not enough results. A little research showed that we were missing some good C books because the publishers didn't categorize them as C books. After a little digging we added much more C code last night and more C++ too. We'll add two new Ajax books on March 1 when they are officially published.
