項目要求
以菜單方式工作管理每個職工的個人信息。
（1）總共有職工若干名，每個職工是一個記錄，包括的信息有：職工號、姓名、性別、出生年月、學歷、職務、部門、工資、住址、電話等等（可以根據自己的需求添加），并且可以對職工信息進行錄入、刪除、修改、瀏覽等操作。
（2）可以按姓名進行查詢。
（3）可以修改職工的信息。
（4）用一個文檔來存儲職工的信息，并實現數據的讀取。
單個職工的頭文件：staff.h
?
#ifndef?STAFF_H_INCLUDED
#define STAFF_H_INCLUDED
//結構體創建
structstaff
{
????charID[10];
????charname[10];
????charsex[10];
????intpay;
????intreward;
????intfactpay;
};
//自定義結構體
typedefstructstaff?staff;
//單個職工信息創建
staff?Createstaff();
//單個職工信息輸出
voidDisplaystaff(staff?staff);
//修改職工信息
voidupdatestaff(staff?*Staff);
#endif // STAFF_H_INCLUDED
?
單個職工的cpp文件：staff.cpp
?
#include#include #include?"staff.h" staff Createstaff() { staff staff; printf("-----------ID----------- "); scanf("%s", staff.ID); printf("-----------name----------- "); scanf("%s", staff.name); printf("-----------sex----------- "); scanf("%s", staff.sex); printf("-----------pay----------- "); scanf("%d", &staff.pay); printf("-----------reward----------- "); scanf("%d", &staff.reward); staff.factpay = staff.pay + staff.reward; ????printf(" "); ????returnstaff; } voidDisplaystaff(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(" "); } voidupdatestaff(staff *Staff) { printf("-----請顯示要修改的數據-------- "); Displaystaff(*Staff); printf("-------請輸入要修改的數據---------"); printf("-----------pay----------- "); scanf("%d", &Staff->pay); printf("-----------reward----------- "); scanf("%d", &Staff->reward); Staff->factpay = Staff->pay + Staff->reward; printf(" "); }

2.鏈表的創建
鏈表的頭文件：linklist.h
?
#ifndef LINKLIST_H_INCLUDED
#define LINKLIST_H_INCLUDED
#include "staff.h"
//鏈表結點創建
structNode
{
structstaff Staff;
structNode *next;
};
//自定義結點
typedefstructNode node;
typedefstructNode *linklist;
//創建鏈表
node *Createlinklist();
//輸出鏈表中的數據
voidDisplaylinklist(node *head);
//按職工號查找職工
node *searchnode(node *head, charID[]);
//按姓名查找職工
voidsearchnodebyname(node *head, charname[]);
//刪除職工
voiddelenode(linklist head, charID[]);
//插入職工
voidinsertnode(linklist head, staff Staff);
//鏈表銷毀
voiddistroylinklist(linklist?head);
#endif // LINKLIST_H_INCLUDED
?
鏈表創建的源程序
?
linklist.cpp #include#include #include #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(inti = 0; i<5; i++) { p = (node *)malloc(sizeof(node)); p->Staff = a[i]; p->next = head->next; head->next = p; } returnhead; } voidDisplaylinklist(node *head) { linklist p; p = head->next; while(p!=NULL) { Displaystaff(p->Staff); p = p->next; } } node *searchnode(node *head, charID[]) { linklist p; p = head; while(p!=NULL&&strcmp(p->next->Staff.ID, ID)!=0) { p = p->next; } returnp->next; } voidsearchnodebyname(node *head, charname[]) { linklist p; p = head; while((p!=NULL)&&(strcmp((p->next)->Staff.name, name)!=0)) { p = p->next; } printf("-----′?è??a--------- "); printf("%s", p->next->Staff.name); printf(" "); } voiddelenode(linklist head, charID[]) { 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======== "); } } voidinsertnode(linklist head, staff Staff) { linklist p; p = (node *)malloc(sizeof(node)); p->Staff = Staff; p->next = head->next; head->next = p; } voiddistroylinklist(linklist head) { linklist p; p = head; while(p!=NULL) { p = p->next; free(p); } }

3.文件存盤
file.h
?
#ifndef FILE_H_INCLUDED #define FILE_H_INCLUDED #include "linklist.h" #include "staff.h" //職工信息存盤 voidsaveinformation(linklist head ); //職工信息加載 voidloadinformation(linklist?head?); #endif // FILE_H_INCLUDED
?
file.cpp
?
#include#include #include #include "file.h" #include "linklist.h" #include "staff.h" voidsaveinformation(linklist h ) { FILE*fp; ????linklist?p; if( (fp = fopen("stu.txt","w") ) == NULL) { printf("Failure to open stu.txt! "); exit(0); ????} for( p = h->next; p; p=p->next ) { fwrite( &(p->Staff), sizeof(node), 1, fp); ????} fclose(fp); } voidloadinformation( linklist h ) { FILE*fp; ????staff?nodeBuffer; if((fp = fopen("stu.txt","r")) == NULL) { printf(" 數據文件丟失或為首次運行, 將加載測試數據 "); return; ????} while( fread(&nodeBuffer, sizeof(node), 1, fp)!=0 ) { insertnode(h, nodeBuffer); ????} }

4.主函數:mainmeun.cpp
?
#include?#include #include "linklist.h" #include "staff.h" #include "file.h" voidmainmeun(linklist head); voidsearchmenu(linklist?head); int main(void) { linklist head=NULL; ????//int?n; //printf("------請輸入你要存的數據---------- "); //scanf("%d", &n); head = Createlinklist(); system("cls"); ????//Displaylinklist(head); mainmeun(head); printf(" "); //loadinformation(head); //saveinformation(head); return0; } voidmainmeun(linklist head) { ????linklist?p; charID[10]; //char name[10]; staff Staff; intselection; intflag = 1; do { printf("=================職工管理系統=================== "); printf("==========1.鏈表輸出=====2.數據查詢===== "); printf("=======3.數據刪除===4.數據修改=====5.添加數據====== "); printf("=======6.鏈表銷毀===7.信息存盤=====8.放棄存盤===== "); ????????printf("================================================== "); printf("======請選擇功能（1~8）："); scanf("%d", &selection); switch(selection) { case1: Displaylinklist(head); break; case2: ????????????searchmenu(head); break; case3: printf("=========請輸入工號========== "); scanf("%s", ID); delenode(head, ID); break; case4: printf("=========請輸入工號========== "); scanf("%s", ID); p = searchnode(head, ID); ????????????updatestaff(&(p->Staff)); break; case5: printf("========添加數據========="); Staff = Createstaff(); insertnode(head, Staff); break; case6: distroylinklist(head); break; case7: loadinformation(head); ????????????saveinformation(head); break; case8: flag = 0; ????????????break; } }while(flag == 1); ????printf("========BYE=====BYE======"); } voidsearchmenu(linklist head) { linklist p; intflag = 1; charID[10]; ????charname[10]; do { printf("=========查找菜單=========== "); printf("===1.ID======2.name====3.退出==== "); ????????printf("================================= "); intselection; printf("==請選擇功能（1~3）："); scanf("%d", &selection); switch(selection) { case1: printf("=====請輸入ID======= "); scanf("%s", ID); p = searchnode(head, ID); Displaystaff(p->Staff); ????????????break; case2: printf("=====請輸入name====== "); scanf("%s", name); searchnodebyname(head, name); ????????????break; case3: flag = 0; break; } system("pause"); ????????system("cls"); }while(flag == 1); }
