说明：  C语言趣味程序百例精解，是PDF格式。里面有很多趣味的例子，大大小小的算法都有，可谓是算法的经典。这个是学习算法的好资料，在学习中找到趣味，完全不同于其他资料的算法枯燥无味(C language program 100 cases of sperm interesting solution is in PDF format. There are many interesting examples of both large and small algorithm, the algorithm can be described as classic. This is a learning algorithm is good information, in learning to find interesting information is completely different from other algorithms dull)

说明：  steganography challenge in c++

说明：  伪普法声波，弹性波正演模拟，plm边界吸收(Pseudo-Franco-Prussian acoustic, elastic wave forward modeling, plm boundary absorption)

说明：  利用打印驱动程序生成SVG文件，很好的源代码下载把(Use printer driver to generate SVG documents, a very good source code to download the)

建立r树，使用c++完成，对于学习树的建立很有好处(create r-tree，use c++)

　我们知道，Visual C++的CBitmap类和静态图片控件的功能是比较弱的，它只能显示出在资源中的图标、位图、光标以及图元文件的内容，而不像VB中的Image控件可以显示出绝大多数的外部图像文件(BMP、GIF、JPEG等)。因此，想要在对话框或其他窗口中显示外部图像文件则只能借助于第三方提供的控件或代码。现在，MFC和ATL共享的新类CImage为图像处理提供了许多相应的方法，这使得Visual C++在图像方面的缺憾一去不复返了。(We know that the Visual C++ the CBitmap class and static picture control function is relatively weak, it only shows the icon resources, bitmaps, cursors, as well as the contents of the metafile, rather than the Image control in VB show the vast majority of external image files (BMP, GIF,, JPEG, etc.). Therefore, I want to display external image files in a dialog or other window only by means of third party controls or code. Now, new class CImage MFC and ATL shared many of the corresponding method for image processing, which makes the Visual C++ of defects in the image is gone forever.)
