C语言课程设计：职工管理系统！

 

项目要求

以菜单方式工作管理每个职工的个人信息。

（1）总共有职工若干名，每个职工是一个记录，包括的信息有：职工号、姓名、性别、出生年月、学历、职务、部门、工资、住址、电话等等（可以根据自己的需求添加），并且可以对职工信息进行录入、删除、修改、浏览等操作。

（2）可以按姓名进行查询。

（3）可以修改职工的信息。

（4）用一个文档来存储职工的信息，并实现数据的读取。

单个职工的头文件：staff.h

 

#ifndef STAFF_H_INCLUDED
#define STAFF_H_INCLUDED


//结构体创建
structstaff
{
    charID[10];
    charname[10];
    charsex[10];
    intpay;
    intreward;
    intfactpay;
};


//自定义结构体
typedefstructstaff staff;
//单个职工信息创建
staff Createstaff();
//单个职工信息输出
voidDisplaystaff(staff staff);
//修改职工信息
voidupdatestaff(staff *Staff);
#endif // STAFF_H_INCLUDED

 

单个职工的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("-----请显示要修改的数据--------
");
    Displaystaff(*Staff);


    printf("-------请输入要修改的数据---------");
    printf("-----------pay-----------
");
    scanf("%d", &Staff->pay);
    printf("-----------reward-----------
");
    scanf("%d", &Staff->reward);
    Staff->factpay = Staff->pay + Staff->reward;
    printf("
");


}

 

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
structNode
{
    structstaff Staff;
    structNode *next;
};
//自定义结点


typedefstructNode node;
typedefstructNode *linklist;
//创建链表
node *Createlinklist();
//输出链表中的数据
voidDisplaylinklist(node *head);
//按职工号查找职工
node *searchnode(node *head, charID[]);
//按姓名查找职工
voidsearchnodebyname(node *head, charname[]);
//删除职工
voiddelenode(linklist head, charID[]);
//插入职工
voidinsertnode(linklist head, staff Staff);
//链表销毁
voiddistroylinklist(linklist head);
#endif // LINKLIST_H_INCLUDED

 

链表创建的源程序

 

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("-----´ËÈËΪ---------
");
    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.文件存盘

file.h

 

#ifndef FILE_H_INCLUDED
#define FILE_H_INCLUDED
#include "linklist.h"
#include "staff.h"
//职工信息存盘
voidsaveinformation(linklist head );
//职工信息加载
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("
	数据文件丢失或为首次运行, 将加载测试数据
");
        return;
    }
     while( fread(&nodeBuffer, sizeof(node), 1, fp)!=0 )
    {
        insertnode(h, nodeBuffer);
    }
}

 

4.主函数:mainmeun.cpp
