Technical books are expensve.
Yeah, technical books are expen$ive! You can probably find a used copy online... maybe an older edition. (I'm still using an outdated 4th edition.) Or, just wait awhile... the dollar gets weaker every day! :D
I think most of my computer / programming books have cost about $30 USD. I don't think I've ever spent less than $20.... about the same price as the typical "best sellers." It's not unusual to spend $80 for a textbook.
The best deal is Thinking in C++, by Bruce Eckel. It comes in two volumes, which you can download FREE in PDF format, or purchase hard copies ($70 for the pair). This is an intermediate to advanced book. (It was actually written as a beginning C++ book for experienced C programmers.)
Some popular books and amazon.com prices:
The C++ Programmig Language, by Bjarne Stroustrup ($49.39)
Accelerated C++, by Koenig, & Moo ($33.81)
C++ How To Program, by Deitel & Deitel ($78.66)
