5、·121、实验目的、内容通过课程设计,能够熟练运用C++进行面向对象编程,建立对象模型,降低软件的复杂性,改善软件的重用性和维护性,提高软件的生产效率,全面掌握面向对象编程技术.要求学生在指导老师的指导下,独立完成实习课题的全部内容,包括:(1)通过调查研究和上机实习,收集和调查有关技术资料;(2)掌握设计课题的基本步骤和方法;17(1)根据课题的要求进行上机实验调试.2、题目一:比赛求平均分2.1程序内容在体育、文艺比赛及选举等打分类项目中，为了公平起见，往往n个评委打出分数后，要去掉一个最高分和一个最低分，然

6、后求取平均得分。当n较大时（本题设为9），则应取掉两个最高分和两个最低分，然后求取平均分。编程实现该算法。2.2实验程序设计及结构(1)需求分析:输入9个评委所打分数,程序运行最后结果为去掉最高分和最低分后的平均分.(2)设计结构:总体结构数据结构17从a[0]到a[9]依次为9位评委的打分.2.3设计过程(1)建立iostream/ofstream/fstream、输入、输出、输入输出流对象，建立ifndef,define预编命令，STRUCT数据.(2)根据流程图,建立main函数,并运用for循环.(3)运

7、行main函数进行调试.2.4运行结果173、题目二:火柴游戏3.1程序内容:23根火柴游戏:两个游戏者开始拥有23根火柴(或小棒)。每个游戏者轮流移走１根、２根或３根火柴，拿到最后一根火柴的就算输了。编一程序与计算机玩这个游戏。3.2实验程序设计(1)需求分析:运行程序能使人与计算机进行23根火柴游戏。(2)设计思路:使计算机能最先使火柴变成4或4以下计算机就能赢了。3.3设计过程(1)建立iostream/ofstream/fstream、输入、输出、输入输出流对象，建立ifndef,define预编命令，S

8、TRUCT数据.（2）根据设计思路运用if判断语句设计（3）建立main函数（4）运行main函数调试173.4运行结果4、题目三:足球比分4.1设计内容：问题描述足球联赛采用主客场双循环赛制，胜一场得3分，平局各得1分，负一场得017分，联赛排名以积分多者在前，当两队（或多队）积分相同时，则净胜球（即进球数与失球数之差）多者在前，若净胜球相同，则进球数多者在前，若仍相同
