本文实例为大家分享了C++职工管理系统实例代码
1.单个职工的头文件
staff.h
#ifndef STAFF_H_INCLUDED #define STAFF_H_INCLUDED //结构体创建 struct staff { char ID[10]; char name[10]; char sex[10]; int pay; int reward; int factpay; }; //自定义结构体 typedef struct staff staff; //单个职工信息创建 staff Createstaff(); //单个职工信息输出 void Displaystaff(staff staff); //修改职工信息 void updatestaff(staff *Staff); #endif // STAFF_H_INCLUDED 单个职工的cpp文件 staff.cpp #include <stdio.h> #include <stdlib.h> #include "staff.h" staff Createstaff() { staff staff; printf("-----------ID-----------n"); scanf("%s", staff.ID); printf("-----------name-----------n"); scanf("%s", staff.name); printf("-----------sex-----------n"); scanf("%s", staff.sex); printf("-----------pay-----------n"); scanf("%d", &staff.pay); printf("-----------reward-----------n"); scanf("%d", &staff.reward); staff.factpay = staff.pay + staff.reward; printf("n"); return staff; } void Displaystaff(staff staff) { printf("%10s", staff.ID); printf("%10s", staff.name); printf("%10s", staff.sex); printf("%10d", staff.pay); printf("%10d", staff.reward); printf("%10d", staff.factpay); printf("n"); } void updatestaff(staff *Staff) { printf("-----请显示要修改的数据--------n"); Displaystaff(*Staff); printf("-------请输入要修改的数据---------"); printf("-----------pay-----------n"); scanf("%d", &Staff->pay); printf("-----------reward-----------n"); scanf("%d", &Staff->reward); Staff->factpay = Staff->pay + Staff->reward; printf("n"); }
2.链表的创建
链表的头文件
linklist.h
#ifndef LINKLIST_H_INCLUDED #define LINKLIST_H_INCLUDED #include "staff.h" //链表结点创建 struct Node { struct staff Staff; struct Node *next; }; //自定义结点 typedef struct Node node; typedef struct Node *linklist; //创建链表 node *Createlinklist(); //输出链表中的数据 void Displaylinklist(node *head); //按职工号查找职工 node *searchnode(node *head, char ID[]); //按姓名查找职工 void searchnodebyname(node *head, char name[]); //删除职工 void delenode(linklist head, char ID[]); //插入职工 void insertnode(linklist head, staff Staff); //链表销毁 void distroylinklist(linklist head); #endif // LINKLIST_H_INCLUDED
链表创建的源程序
linklist.cpp
#include <stdio.h> #include <stdlib.h> #include <string.h> #include "staff.h" #include "linklist.h" node *Createlinklist() { node *head, *p; head = (node *)malloc(sizeof(node)); head->next = NULL; staff a[100] = {{"11111", "mmm", "f", 12000, 2000, 14000}, {"22222", "aaa", "m", 13000, 3000, 16000}, {"33333", "sss", "f", 15000, 3000, 18000}, {"44444", "fff", "m", 17000, 8000, 25000}, {"55555", "ggg", "f", 20000, 5000, 25000}}; for(int i = 0; i<5; i++) { p = (node *)malloc(sizeof(node)); p->Staff = a[i]; p->next = head->next; head->next = p; } return head; } void Displaylinklist(node *head) { linklist p; p = head->next; while(p!=NULL) { Displaystaff(p->Staff); p = p->next; } } node *searchnode(node *head, char ID[]) { linklist p; p = head; while(p!=NULL&&strcmp(p->next->Staff.ID, ID)!=0) { p = p->next; } return p->next; } void searchnodebyname(node *head, char name[]) { linklist p; p = head; while((p!=NULL)&&(strcmp((p->next)->Staff.name, name)!=0)) { p = p->next; } printf("-----´ËÈËΪ---------n"); printf("%s", p->next->Staff.name); printf("n"); } void delenode(linklist head, char ID[]) { linklist p; p = head; while(p->next&&(strcmp(p->next->Staff.ID, ID)!=0)) { p = p->next; } if(p->next) { p->next = p->next->next; } else { printf("=====NO FOUND========n"); } } void insertnode(linklist head, staff Staff) { linklist p; p = (node *)malloc(sizeof(node)); p->Staff = Staff; p->next = head->next; head->next = p; } void distroylinklist(linklist head) { linklist p; p = head; while(p!=NULL) { p = p->next; free(p); } }
3.文件存盘
file.h
#ifndef FILE_H_INCLUDED #define FILE_H_INCLUDED #include "linklist.h" #include "staff.h" //职工信息存盘 void saveinformation(linklist head ); //职工信息加载 void loadinformation(linklist head ); #endif // FILE_H_INCLUDED file.cpp #include <stdio.h> #include <string.h> #include <stdlib.h> #include "file.h" #include "linklist.h" #include "staff.h" void saveinformation(linklist h ) { FILE *fp; linklist p; if ( (fp = fopen("stu.txt","w") ) == NULL) { printf("Failure to open stu.txt!n"); exit(0); } for ( p = h->next; p; p=p->next ) { fwrite( &(p->Staff), sizeof(node), 1, fp); } fclose(fp); } void loadinformation( linklist h ) { FILE *fp; staff nodeBuffer; if ((fp = fopen("stu.txt","r")) == NULL) { printf("nt数据文件丢失或为首次运行, 将加载测试数据n"); return ; } while( fread(&nodeBuffer, sizeof(node), 1, fp)!=0 ) { insertnode(h, nodeBuffer); } }
4.主函数
mainmeun.cpp
#include <stdio.h> #include <stdlib.h> #include "linklist.h" #include "staff.h" #include "file.h" void mainmeun(linklist head); void searchmenu(linklist head); int main(void) { linklist head=NULL; //int n; //printf("------请输入你要存的数据----------n"); //scanf("%d", &n); head = Createlinklist(); system("cls"); //Displaylinklist(head); mainmeun(head); printf("nn"); //loadinformation(head); //saveinformation(head); return 0; } void mainmeun(linklist head) { linklist p; char ID[10]; //char name[10]; staff Staff; int selection; int flag = 1; do { printf("=================职工管理系统===================n"); printf("==========1.链表输出=====2.数据查询=====n"); printf("=======3.数据删除===4.数据修改=====5.添加数据======n"); printf("=======6.链表销毁===7.信息存盘=====8.放弃存盘=====n"); printf("==================================================n"); printf("======请选择功能（1~8）："); scanf("%d", &selection); switch(selection) { case 1: Displaylinklist(head); break; case 2: searchmenu(head); break; case 3: printf("=========请输入工号==========n"); scanf("%s", ID); delenode(head, ID); break; case 4: printf("=========请输入工号==========n"); scanf("%s", ID); p = searchnode(head, ID); updatestaff(&(p->Staff)); break; case 5: printf("========添加数据========="); Staff = Createstaff(); insertnode(head, Staff); break; case 6: distroylinklist(head); break; case 7: loadinformation(head); saveinformation(head); break; case 8: flag = 0; break; } }while(flag == 1); printf("========BYE=====BYE======"); } void searchmenu(linklist head) { linklist p; int flag = 1; char ID[10]; char name[10]; do { printf("=========查找菜单===========n"); printf("===1.ID======2.name====3.退出====n"); printf("=================================n"); int selection; printf("==请选择功能（1~3）："); scanf("%d", &selection); switch(selection) { case 1: printf("=====请输入ID=======n"); scanf("%s", ID); p = searchnode(head, ID); Displaystaff(p->Staff); break; case 2: printf("=====请输入name======n"); scanf("%s", name); searchnodebyname(head, name); break; case 3: flag = 0; break; } system("pause"); system("cls"); }while(flag == 1); }
