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("-----------reward-----------
");
    scanf("%d", &Staff->reward);

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

?
