Per averlo devi acquistare la versione cartacea del testo, a questo punto conviene comprare un libro sul linguaggio C se ne senti il bisogno.The printed book contains a CD ROM training course that gently introduces you to the C syntax that you need to understand in order to take on C++ or Java. The CD is called Thinking in C: Foundations for Java & C++. Originally we sold this CD separately, but now it is only available bound into the printed versions of either Thinking in C++, 2nd edition or Thinking in Java, 2nd edition (the cost of the book including the CD is actually cheaper that the former cost of the CD alone).
