C++实现简单的职工管理系统实训代码_C 语言

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("\n\t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("\n\n");
  //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);
}
