c语言课程设计报告书题目：职工工资管理学号：0911080008姓名：李志学号：0911060010姓名：刘凯学号：0904080001姓名：张琛 1 功能需求如下：系统概述添加模块：添加职工或工资的信息删除模块：能通过姓名或者工号删除职工信息修改模块：修改职工信息查询模块：能通过姓名或者工号查询职工信息显示模块：显示全部职工信息文件管理模块：负责源数据文件的管理，包括新建、读取和保存源数据2总体设计系统模块结构框图 职工工资管理添加模块删除模块修改模块查询模块显示模块文件管理模块按姓名按工号按姓名按工号新建记录数据文件读取记录数据文件保存记录数据文件在各模块处用指针函数来使用后面的保存记录数据文件进行保存。3详细设计 （参数代码如下）# include # include # include /*宏定义*/# define n 100 /*假设工人个数是100*/# define header1 -n # define header2 | number | name | psex | age | time | ywage | ykou | pwage |n# define header3 |-|-|-|-|-|-|-|-|n# define format |%-8d|%-8s|%-8s|%-7d|%-6d|%-7d|%-6d|%-7d|n# define data p-num ,p-name,p-sex,p-age,p-time,p-ywage,p-ykou,p-pwage# define end -n/*/typedef struct workint num; /*/char name10; char sex10;int age; /*/ int time; /*/int ywage; /*/int ykou; /*/int pwage; /*/work;/*/typedef struct pointer_infowork*phead; /*/int count; /*/char fname10; /*/ int saveflag; /*/pi; /*/void menu(); void add(pi*);void del(pi*);void save(pi*pi);void modify(pi*pi);void qur(pi*pi);void load(pi*pi);void new(pi*pi);void disp(pi*);void wrong();void printheader();void main()int sel;work *pwork;pi pi;pwork = (work*)malloc(n * sizeof(work);pi.phead = pwork;pi.count = 0;pi.fname0 = 0;pi.saveflag = 0;/*显示主函数*/menu();printf(please input your choice 05:);do scanf(%d,&sel); if (sel = 0) /*if (pi.saveflag =1) if (strlen(pi.fname)save(&pi);else new(&pi);save(&pi); */break;switch(sel) case 1:add(&pi);break; case 2:del(&pi);break;case 3:modify(&pi);break;case 4:qur(&pi);break; case 5:disp(&pi);break;default:wrong();break; while(1);pwork = pi.phead;free(pwork);void printheader() printf(header1);printf(header2);printf(header3);void menu()system(cls);printf( the workers grade wage system n);printf(*menu*n);printf( * 1 添加 *n);printf( * 2 删除 *n);printf( * 3 修改 *n);printf( * 4 查询 *n);printf( * 5 显示 *n);printf( * 0 退出 *n);printf (*n);void wrong( )printf(n*error :input has wrong !
