1、一、 题目要求设计校际运动会管理系统，实现学校、运动员信息和运动项目的录入，比赛结果的输入，各个学校比赛结果的查询，生成团体总分报表，查看参赛学校信息和比赛项目信息。要求功能选择用菜单实现。二、 需求分析 根据题目要求应提供键盘式菜单实现功能选择，还应提供信息的输入操作，由于在程序中提供查询功能所以应有显示、查找等操作。三、 总体设计根据上面的需求分析，可以将这个系统的设计分为 1、信息输入模块 2、比赛结果录入模块 3、查询模块。具体校际运动会管理系统分为 信息的输入、结果的输入、学校各个项目的得分的查寻、总体报表的生成。四、 详细设计 1、主函数主函数一般设计的比较简洁，只提供输入，处理和
2、输出部分的函数调用。其中功能模块用菜单方式选择。流程图程序main()menu();/*menu 是菜单函数 */菜单函数程序如下：menu() int o,n;do puts(“tt*MENU*“);puts(“nntt 1.The information to writeinn“);puts(“tt 2.The race result records to writeinn“);显示一系列功能选项输入 n，判断 n 是否是 09根据 n 的值调用各功能模块函数YNputs(“tt 3.Search the informationn“);puts(“tt 4.Exitn“);puts(“nt
3、t*“);puts(“nnChoice you number:“);scanf(“%d“,if(n4)o=1;getchar(); /*对选择的数字进行判断*/else o=0;while(o=1); /*选择功能*/switch(n) case 1:writein();break; /*信息输入模块*/case 2:resultin();break; /*比赛结果输入模块 */case 3:search();break; /*查询模块*/case 4:exit(0); /*退出*/各个模块的设计1、 信息输入数据结构数据结构采用结构体的形式，包括学校、项目、运动员三个结构体。比如学校结构体成
4、员包括学校校名、竞赛项目、得分；项目结构体成员包括项目名、权值。struct student char shool10;char name10;char item10;char sex;int position;int mark;stuC; /*stuN中每个数组元素对应一个学生*/struct item char name10;char sex;int mark;itC; /*itC中每个数组元素对应一个项目 */struct shool char name10;char item10;int mark;shoC /* shoC每个数组元素对应一个学校;*/ 信息输入模块根据题意把与运动员的
5、学校、名字、项目、性别、名次、分数作为结构体成员，如果要存放若干个运动员的信息就用结构体数组。struct student char shool10;char name10;char item10;char sex;int position;int mark;stuC; /*stuC中每个数组元素对应一个运动员*/stuC中的 C 为运动员的个数，程序中采用宏定义的方式定义C=100，C 的值可随时在源程序中改变。 图 2 输入模块流程图/*输入模块*/writein() /*输入模块*/ int t,r,i=0;extern j;char F,M;y=1; printf(“nPlease w

8、运动员的成绩，并由用户选择或定义各名次的分数。流程图 提醒用户先输入运动员信息输入学校的代号、男女运动项目的代号用户选择或定义各名次的分数输入成绩并反回主函数程序/*结果录入模块*/resultin() /*结果录入模块*/ int h,r; extern N,M,W,y;if(y=0) printf(“Please establish system first!nPress any key +enter to menu “);scanf(“%d“, /*提醒用户输入运动员的基本信息*/menu();printf(“nThe number of shool attended is:“);sca
