跪求C语言中得#include "cv.h"库和#include "highgui.h"库，要能用的，包含头文件和源文件，谢谢。

Posted 2023-04-30

这两个是计算机视觉库opencv中的头文件，可以在http://opencv.willowgarage.com/wiki/InstallGuide找到下载方式。其稳定版本在http://sourceforge.net/projects/opencvlibrary上有下载，最新代码可通过svn检出https://code.ros.org/svn/opencv/trunk获得。 参考技术A 是opencv的库。去下载opencv安装一下。
http://www.opencv.org.cn/ 参考技术B 你这 2个头文件 是 一些程序员自己写的 没 地方找阿 “” 引号 的是 私人的
<> 这个弄起来的 才有的找

学生信息管理系统(C语言版)

用C/C++编写的学生信息管理系统，最好有课程设计的论文，如果没有的话只有做好的系统也可以，代码要求50%以上注释！
最好是把整套完整系统的下载地址告诉我。万分感谢！！如果可以用的话，一定再追加50分！
