类似于病毒的可以无限复制的程序。
程序附有源码，可以加一句fopen之类的。

这是一个用纯C语言写的程序，用到的是TCP/IP网络通信原理，这是个功能比好的程序，包含了用户注册，用户登录，密码保护，修改密码，在线用户查询，用户上线通知等基本功能，我个人也花了比较长的时间来写，由于我个人花了比较多的心血，所以下载的资源分高了点，希望不要见怪上传的包中，包含了所有的源代码，绝对可运行使用，不需要配置任何环境不过里面的fopen打的文件路径，自己按照实际情况改下吧

I_rgb=imread('lena.jpg');%subplot(2,2,1),imshow(I_rgb),title('lena-rgb')I_gray=rgb2gray(I_rgb);%subplot(2,2,2),imshow(I_gray),title('lena-gray')I=imresize(I_gray,0.25);%subplot(2,2,3),imshow(I),title('lena-qtr')fid=fopen('./lena.txt','wt');

练习一：编写一个程序统计文本文件英文字母个数，不区分大小写，屏幕输出每个字母出现的次数。
参考：文件操作函数，fopen,fclose,fread,fgetc；
使用MSDN查找相关帮助；
要求：代码的编写、变量定义等应以《CodingStandard》为依据，完成题目功能。
例如：SumLetter.exesample.txtoutput: A:25 B:3 C:0 D:10 E...

Vivado及ISE仿真中文件读取操作整理：测试数据以txt文本形式存储，然后添加到工程中，在使用$readmemb的时候，需要txt文本的全部路径。
个人尝试了先使用fopen打开文本，然后再使用$readmemb读取，没有成功，好像不能使用fopen打开后读取，而是直接在$readmemb中使用文件绝对路径。
亲测可行。

作为云时代的程序员，如果你还在使用fopen()、fclose()之类的函数，那你就OUT了！自从阿里云推出开放存储服务（OpenStorageService，简称OSS）后，越来越多的技术牛人们开始将他们的应用和产品迁移到OSS这个云存储平台上来。
在上期《凌云》杂志中，我们向大家简要介绍了如何使用OSS——《用云存储和CDN轻松搞定网站图片》。
在本期中，我们再讲解一些使用OSS开发的实用技巧，希望能起到抛砖引玉的效果。
OSS对外提供的RESTful风格的API接口遵循HTTP协议，因而任何语言和工具只要按照OSSAPI文档定义的规则发送合法的HTTP请求，就可以使用OSS服务。

在日常工作中，钉钉打卡成了我生活中不可或缺的一部分。然而，有时候这个看似简单的任务却给我带来了不少烦恼。 每天早晚，我总是得牢记打开钉钉应用，点击"工作台"，再找到"考勤打卡"进行签到。有时候因为工作忙碌，会忘记打卡，导致考勤异常，影响当月的工作评价。而且，由于我使用的是苹果手机，有时候系统更新后，钉钉的某些功能会出现异常，使得打卡变得更加麻烦。 另外，我的家人使用的是安卓手机，他们也经常抱怨钉钉打卡的繁琐。尤其是对于那些不太熟悉手机操作的长辈来说，每次打卡都是一次挑战。他们总是担心自己会操作失误，导致打卡失败。 为了解决这些烦恼，我开始思考是否可以通过编写一个全自动化脚本来实现钉钉打卡。经过一段时间的摸索和学习，我终于成功编写出了一个适用于苹果和安卓系统的钉钉打卡脚本。
