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);
}
