算24点”作为一种扑克牌智力游戏，游戏内容为从一副牌中抽去大小王2张，任意抽取4张牌（称牌组），用加、减、乘、除（可加括号）把牌面上的数算成24，每张牌必须用一次且只能用一次。我们可以人工计算，当然也可以用计算机来处理。本程序主要是借助计算机利用设计好的算法来计算24点问题。 该24点游戏程序内容主要包括界面显示，自动运算24点以及手动计算24点三部分，采用模块化开发方法，并汇编语言编写程序代码。-Count 24 points " as a mental poker game, a game content license from the King of removing the size 2, 4 samples of arbitrary license (a license that group), with add, subtract, multiply, divide (which can be bracketed ) to the surface of the card count as 24, each card must be used once and only once. We can manually, of course, can also be used to deal with the computer. This procedure is the use of the use of computer algorithms designed to calculate the 24 points. The 24-point games, including the contents of the main screen, automatic operation and manual calculation of 24 points, 24 points, three-part, modular development methodology, and assembly language programming code.

在我们生活中，我们很容易通过这个叫张三，那个叫李四，另外一个是王五；那是因为每个人有不同的名子，我们就很快认出，同样，对于要通过一个按键来识别每种不同的功能，我们给每个不同的功能模块用不同的ID号标识，这样，每按下一次按键，ID的值是不相同的，所以单片机就很容易识别不同功能的身份了。-In our lives, we can easily Zhang through this three or four叫李that, another five-Wang it is because everyone has a different name, we quickly identified, and similarly, for a button to pass to identify the different functions of each, we have different functions to each module" s ID number with different logo, so, for every one button press, ID is not the same value, so it is easy to identify the different single-chip function hats.

GDI 即图形设备界面，是 Windows 最重要的部分之一，它大部分由 GDI32.DLL 库中的 API 来处理，GDI 的主要目的之一是支持与设备无关的图形编程，对于 Dos 下的图形编程，很多人可能“心有余悸”，因为PC 中有太多种类的显示卡，而几乎每个显示卡的处理都是不同的，即使后来有了 Vesa 编程，我们还是不能全部撇开具体的硬件，Windows GDI 使我们对图形的编程变得相对简单了很多，由于GDI 是 Windows 最庞大的部分，并不是几句话能讲清楚的，本节要讲的是 Windows 下GDI 的基本处理步骤和简单的位图处理，并没有涉及到 Directx 一类的编程。只希望能对朋友们有所启发。 Windows 并不允许程序员访问显示硬件，它的所有对屏幕的操作是通过环境设备（DC）来处理的，屏幕上的每一个窗口对应一个DC，你可以把一个DC 想象成这个窗口的视频缓冲区，你对DC的操作结果会反映到屏幕上，在窗口的DC之外，你也可以自己建立DC，这相当于建立一个内存中的缓冲区，你对这个DC的操作结果保存在内存中。你也可以用 API 在不同的DC之间拷贝数据，比如说你可以在内存DC 中先建立好数据，然后拷贝到窗口的DC中，就相当于完成了屏幕的刷新。 -err
