C语言课程设计优秀版

1、 C程序课程设计摘要本文程序针对3个候选人投票问题和出租车公司选取3名优秀驾驶员的问题编写了两道程序，通过运用到的结构体的设定、if语句、数组的排序、goto语句构成的循环，关系运算符和关系表达式、逻辑运算及其优先次序等多个C程序设计知识点，最终设定出逻辑思维紧密的候选人投票程序与评分多样化的出租车公司选优秀司机的评分程序。每个程序在体现出操作者需求的同时，也总有它本身一下不足的地方，本文中的程序候选人投票程序有较大的局限性，本文中的投票程序只针对只有3名候选人的情况，如果候选人多的话就不再用；出租车公司选优秀司机的评分程序具有较低的局限性，其中参与评选的司机人数可以随意的设定，只需改动该程序

2、中的自定义常量N，程序用还附有该程序的输入说明，让操作该程序的人简单明了地完成操作任务，但不足的地方是加入操作员输入错误数据时没有错误的提示，也不会返回更改，要求操作员有足够的细心和耐心。 关键词：结构体；数组；循环目录一、选举候选人的投票的程序设计与实现41、程序流程图42、源程序63、结果分析13二、出租车公司选3名优秀司机的评分程序的设计与实现141、程序流程图142、源程序183、结果分析21三、心得体会22四、参考文献23一、选举候选人的投票的程序设计与实现对候选人投票问题的设定一个程序，该程序具有以下功能： （1）设有“现场群众投票”7张、“嘉宾领导投票”3张；（2）设有“弃权”选

3、项；（3）如果在输入候选人名字的错误的时候，系统会给出相应的指示，并返回重新开始选票；（4）在结果中打印各候选人的现场群众投票数和嘉宾领导投票数，以及各候选人得到选票的总数；（5）在结果中打印得票数最高的票数以及相对应候选人的名字；（6）设置程序为如果候选人总得票数相等，那相比较嘉宾领导的投票数，如果嘉宾领导的投票数相等，那就比较现场群众的投票数，如果还相等，那就提示这两个候选人重新投票；1、程序总流程图：Y开始定义一个结构体person，包含数组name、count、sum，并命名为leader定义一个结构体count，包含数组viewer、rater定义整型变量i=0,j=0,z=0,ma

4、x=0,maxi=0,sum=0;定义字符数组viewer_vote，rater_vote;定义一个结构体count，包含数组viewer、raterNi<7分别输入三个候选人名字（name）、群众得票（viewer）、领导得票(rater)总得票（sum）候选人的总得票=群众得票+嘉宾领导投票（leaderi.sum=leaderi.count.viewer+leaderi.count.rater）根据候选人的总得票进行排序选出得票最高的候选人Leadermaxi输出得票最高的候选人；所有候选人的得票情况结束YNj<3输入各嘉宾领导的投票z<3N输入各群众的投票i<7
