Top-down

自顶向下(Top-down)的分析算法通过在最左推导中描述出各个步骤来分析记号串输入。将大型的数字电路设计分割成大小不一的小模块来实现特定的功能,最后通过由顶层模块调用子模块来实现整体功能,这就是Top-down的设计思想。

    Overview In this chapter I introduce Borland C++Builder (BCB) and explain what it is about. I also devote considerable time to explaining the purpose of this book and the philosophy behind my approach to technical writing. Technical subjects covered in this chapter include Creating a simple Multimedia RAD program that plays movies, WAV files, and MIDI files. Shutting down the BCB RAD programming tools and writing raw Windows API code instead. Creating components dynamically on the heap at runtime. Setting up event handlers (closures) dynamically at runtime. A brief introduction to using exceptions. This topic is covered in more depth in Chapter 5, "Exceptions." A brief introduction to ANSI strings. This subject is covered in more depth in Chapter 3, "C++Builder and the VCL." Using the online help. Greping through the include and source files that come with the product and with this book.

  • BREW手机平台下的实例

    BREW手机平台下的实例,实现苹果的移动。 通过按键盘的 “UP”、“Down”、“Left”、“Right”使整个苹果可以在屏幕上自由移动(Step=1),通过按“*”使苹果回到初始位置(屏幕的中间) 1,苹果是由4个对象组合而成,移动的时候如何成为一个整体 2、作为key事件驱动区分各个按键动作 3、苹果的每一次移动都是以上一次苹果的位置为参考

  • CBC下写的串口编程

    CBC下写的串口编程,API函数实例 I wish this site had been around when I was trying to figure out how to make serial communications work in Windows95. I, like many programmers, was hit with the double-whammy of having to learn Windows programming and Win95 serial comm programming at the same time. I found both tasks confusing at best. It was particularly frustrating because I had, over the years, written so much stuff (including lots of serial comm software) for the DOS environment and numerous embedded applications. Interrupt driven serial comm, DMA transfer serial comm, TSR serial comm, C, assembler, various processors... you name it, it had written it. Yet, everything I knew seemed upside-down in the message-driven-callback world of Windows.

    In case you haven t realized it, building computer systems is hard. As the complexity of the system gets greater, the task of building the software gets exponentially harder. As in any profession, we can progress only by learning, both from our mistakes and from our successes. This book represents some of this learning written in a form that I hope will help you to learn these lessons quicker than I did, or to communicate to others more effectively than I did before I boiled these patterns down.

    说明:这个程序与温控仪设置方式一样。SET选择设置模式;LEFT键选择需要设置的位;UP键加置数,如果按住UP键不放就自动向上计数,最大值999;DOWN键减置数,如果按住DOWN键不放就自动向下计数,一直到0。待设置的位是高亮显示的。
