说明：  C++是C语言的继承，它既可以进行C语言的过程化程序设计，又可以进行以抽象数据类型为特点的基于对象的程序设计，还可以进行以继承和多态为特点的面向对象的程序设计。著名编程专家Donald Walk 所著,结合硬件与软件编程，清晰易懂！
(If you already know how to program in any other language you should best skip to the section Understanding Source Files in the Getting Started chapter. You should check also the next section so you can get a feel for what is different from the language you are accustomed to. If this is your first contact with a programming language then continue on reading, take in consideration that the Programming Paradigms section can be hard to digest if you lack some bases, don't despair, the relevant points will be extended when other concept are introduced, that section is provided to give you a mental framework to help you not only to understand C++ but to let you easily adapt to (and from) other languages that share those concepts.)
