安卓版微信源代码,好学的同学可以下载下来自己学习下,有什么需求可以发信息给我

这是一个微信小程序版的论坛社区系统源代码分享，显示最新、最热的社区热点内容，界面也是社区类型APP习惯的风格，用户可发表内容，将论坛搬到了手机微信中，现在互动性的系统很丰富了，在以前，像论坛一类的系统很火的，本源码更多的是参考性的范例。

新闻类微信 APP客户端程序源码，利用微信小程序官方开发者工具开发，使用截获的搜狗搜索GET请求包有关微信平台热门新闻与关键词的数据生成的新闻列表浏览。 　　本小程序实例说明： 　　* 首页到新闻列表详情页的路由跳转 　　* MODAL框绑定显示新闻详情 　　使用和配置方法：克隆本项目代码到本地 　　* 打开微信开发者工具； 　　* 添加项目->选择本项目目录->编译执行； 　　预览： 　　界面简陋，请多包涵。

Code from Programming Pearls Column 1: Programs for sorting integers bitsort.c -- Sort with bit vectors. sortints.cpp -- Sort using C++ STL sets. qsortints.c -- Sort with C library qsort. bitsortgen.c -- Generate random integers for sorting. Column 2: Test and time algorithms rotate.c -- Three ways to rotate the elements of a vector. The next two program are used in a pipeline to compute all anagrams in a dictionary sign.c -- Sign each word by its letters in sorted order. squash.c -- Put each anagram class on a single line. Column 5: Scaffolding for testing and timing search functions search.c -- Linear and binary search. Column 7: Tiny experiment on C run times timemod0.c -- Edit main to time one operation. Column 8: Compute the maximum-sum subsequence in an array maxsum.c -- Time four algs: n3, n2, n log n, n. Column 9: Code tuning programs genbins.c -- Profile this, then try a special-purpose allocator. macfun.c -- Time the cost of macros and functions. The column also uses rotate.c (Column 2), search.c (Column 5) and maxsum.c (Column 8). Column 11: Test and time sorting algorithms sort.cpp -- Mostly C, but also C++ sort function. SortAnim.java -- Animate those sort functions in Java. Column 12: Generate a sorted list of random integers sortedrand.cpp -- Several algorithms for the task. Column 13: Set representations for the problem in Column 12 sets.cpp -- Several data structures for sets. genbins.c (Column 9) implements the bin data structure in C. Column 14: Heaps priqueue.cpp -- Implement and test priority queues. The column also uses sort.c (Column 11) for heapsort. Column 15: Strings wordlist.cpp -- List words in the file, using STL set. wordfreq.cpp -- List words in the file, with counts, using STL map. wordfreq.c -- Same as above, with hash table in C. longdup.c -- Find long repeated strings in input. markov.c -- Generate random text from input. markovhash.c -- Like markov.c, but with hashing. markovlet.c -- Letter-level markov text, simple algorithm. Appendix 3: Cost Models spacemod.cpp -- Space used by various records. timemod.c -- Table of times used by various C constructs.
