本书所有程序代码都是由字处理软件自动包括在正文中的它们直接取自编译好的文

件因此书内印刷的代码都应能正常工作其中不存在任何输入或打字错误不会造成编

译错误会造成编译错误的代码已用注释//!标出所以很容易发现也很容易用自动方式进

行测试。-Book all by word processing software program code automatically included in the text of which is taken directly from compiled files so the code printed inside the book should be able to work in which there is no input or typographical errors will not cause a compilation error resulting code is compiled with the wrong comment//! marked so it is easy to find very easy to use automatic mode for testing.
