2、求编程实现各种进制的转换。任务要求：1）阐述设计思想,画出流程图;2）需要对哈夫曼编码/译码的相关原理有所了解，设计数据结构，建立必要的信息数据文件（最好存储成外部文件），并分析完成用户所需的基本操作功能；3）实现给定信息的编码和译码功能；4）应有较好的界面设计，说明程序测试方法；5）按照格式要求完成课程设计说明书。设计要求:1）问题分析和任务定义：根据设计题目的要求，充分地分析和理解问题，明确问题要求做什么？（而不是怎么做？）限制条件是什么？确定问题的输入数据集合。2）逻辑设计：对问题描述中涉及的操作对象定义相应的数据类型，并按照以数据结构为中心的原则划分模块，定义主程序模块和各抽象数据类型

3、。逻辑设计的结果应写出每个抽象数据类型的定义（包括数据结构的描述和每个基本操作的功能说明），各个主要模块的算法，并画出模块之间的调用关系图；3）详细设计：定义相应的存储结构并写出各函数的伪码算法。在这个过程中，要综合考虑系统功能，使得系统结构清晰、合理、简单和易于调试，抽象数据类型的实现尽可能做到数据封装，基本操作的规格说明尽可能明确具体。详细设计的结果是对数据结构和基本操作做出进一步的求精，写出数据存储结构的类型定义，写出函数形式的算法框架；4）程序编码：把详细设计的结果进一步求精为程序设计语言程序。同时加入一些注解和断言，使程序中逻辑概念清楚；5）程序调试与测试：能够熟练掌握调试工具的各种

4、功能，设计测试数据确保程序正确。调试正确后，认真整理源程序及其注释，形成格式和风格良好的源程序清单和结果；6）结果分析：程序运行结果包括正确的输入及其输出结果和含有错误的输入及其输出结果。算法的时间、空间复杂性分析；7）编写课程设计报告；以上要求前三个阶段的任务完成后，将设计说明书的草稿交指导老师面审，审查合格方可进入后续阶段的工作。设计工作结束，经指导老师验收合格后将设计说明书装订，并答辩。指导教师（签字）：教研室主任（签字）：文档编码:CB9L8J1T7E7 HV7P3D5G1X1 ZV4D2R2S3Y1文档编码:CB9L8J1T7E7 HV7P3D5G1X1 ZV4D2R2S3Y1文档编

26、的独立思考，还借助各种参考文献来帮助我们完成系统。更为重要的是，我们同学之间加强了交流，在对问题的认识方面可以交换不同的意见。同时，师生之间的互动也随之改善，我们可以通过具体的实例来从老师那学到更多的实用的知识。数据结构课程具有比较强的理论性，同时也具有较强的可应用性和实践性。课程设计是一个重要的教学环节。我们在一般情况下都能够重视实验环节，但是容易忽略实验的总结，忽略实验报告的撰写。通过这次实验让我们明白：作为一名大学生必须严格训练分析总结能力、书面表达能力。需要逐步培养书写科学实验报告以及科技论文的能力。只有这样，我们的综合素质才会有好的提高。文档编码:CB9L8J1T7E7 HV7P3D

34、一文件中的编码编码进行破译。具体介绍：在本课题中，我们在硬盘D盘中预先建立一个哈夫曼.txt 文档，在里面编辑一篇文章(大写)。然后运行程序，调用 fileopen()函数读出该文章，显示在界面；再调用 jsq()函数对该文章的字符种类进行统计，并对每个字符的出现次数进行统计，并且在界面上显示；然后以每个字符出现次数作为权值，调用ChuffmanTree()函数构建哈夫曼树；并调用print1()和 print2()函数将哈夫曼的存储结构的初态和终态进行输出。然后哈夫曼树进行编码，再对另一文件哈夫曼译码.txt 编码进行译码，再输出至界面。至此，整个工作就完成了。文档编码:CB9L8J1T7E

42、ialization）。从文件哈夫曼.txt 读入字符集,，统计字母个数作为权值，建立赫夫曼树。(2)编码（Encoding）。利用已建好的赫夫曼树（如不在内存，则从文件中读入），对哈夫曼树进行编码，然后将结果存入文件哈夫曼译码.txt 中。(3)译码（Decoding）。利用已建好的赫夫曼树将文件哈夫曼译码.txt 中的代码进行译码3.2 部分函数介绍从硬盘读取字符串fileopen(参数)建立 HuffmanTree 通过三个函数来实现：void select(参数)说明：在ht1.k中选择 parent为 0 且权值最小的两个根结点的算法int jsq(参数)说明：统计字符串中各种字母的
