The example of this article for you to share C++ staff management system example code, for your reference, the specific content is as follows

1. Individual employee's header file

staff.h


#ifndef STAFF_H_INCLUDED
#define STAFF_H_INCLUDED
 
// Structure creation 
struct staff
{
 char ID[10];
 char name[10];
 char sex[10];
 int pay;
 int reward;
 int factpay;
};
// Custom structure 
 
typedef struct staff staff;
// Individual employee information creation 
staff Createstaff();
// Individual employee information output 
void Displaystaff(staff staff);
// Modify employee information 
void updatestaff(staff *Staff);
 
#endif // STAFF_H_INCLUDED
 
 
 single-worker cpp file 
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("----- Please display the data to be modified --------\n");
 Displaystaff(*Staff);
 
 printf("------- Please enter the data to modify ---------");
 printf("-----------pay-----------\n");
 scanf("%d", &Staff->pay);
 printf("-----------reward-----------\n");
 scanf("%d", &Staff->reward);
 Staff->factpay = Staff->pay + Staff->reward;
 printf("\n");
 
}

2. Creation of linked lists

The header file of the linked list
linklist.h


#ifndef LINKLIST_H_INCLUDED
#define LINKLIST_H_INCLUDED
#include "staff.h"
// List node creation 
struct Node
{
 struct staff Staff;
 struct Node *next;
};
// Custom node 
 
typedef struct Node node;
typedef struct Node *linklist;
// Create a list 
node *Createlinklist();
// Output the data in the linked list 
void Displaylinklist(node *head);
// Find the employee by the employee number 
node *searchnode(node *head, char ID[]);
// Find the employee by name 
void searchnodebyname(node *head, char name[]);
// Remove the worker 
void delenode(linklist head, char ID[]);
// Insert the worker 
void insertnode(linklist head, staff Staff);
// List to destroy 
void distroylinklist(linklist head);
 
#endif // LINKLIST_H_INCLUDED

List creation of the source
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("-----´ËÈËÎª---------\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. File saving

file.h


#ifndef FILE_H_INCLUDED
#define FILE_H_INCLUDED
#include "linklist.h"
#include "staff.h"
// Employee information storage 
void saveinformation(linklist head );
// Employee information loading 
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 Data file missing or running for first time ,  The test data will be loaded \n");
 return ;
 }
 
 
 while( fread(&nodeBuffer, sizeof(node), 1, fp)!=0 )
 {
 insertnode(h, nodeBuffer);
 }
 
}

4. The main function

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("------ Please enter the data you want to save ----------\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("================= Staff management system ===================\n");
 printf("==========1. List the output =====2. Data query =====\n");
 printf("=======3. To delete data ===4. Data modification =====5. Add data ======\n");
 printf("=======6. List to destroy ===7. Inventory information =====8. Give up inventory =====\n");
 printf("==================================================\n");
 
 printf("====== Please select function ( 1~8 ) : ");
 scanf("%d", &selection);
 switch(selection)
 {
 case 1:
  Displaylinklist(head);
  break;
 case 2:
  searchmenu(head);
 
  break;
 case 3:
  printf("========= Please enter your job number ==========\n");
  scanf("%s", ID);
  delenode(head, ID);
  break;
 case 4:
  printf("========= Please enter your job number ==========\n");
  scanf("%s", ID);
  p = searchnode(head, ID);
  updatestaff(&(p->Staff));
 
 
  break;
 case 5:
  printf("======== Add data =========");
  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("========= To find the menu ===========\n");
 printf("===1.ID======2.name====3. exit ====\n");
 printf("=================================\n");
 
 int selection;
 printf("== Please select function ( 1~3 ) : ");
 scanf("%d", &selection);
 switch(selection)
 {
 case 1:
  printf("===== Please enter the ID=======\n");
  scanf("%s", ID);
  p = searchnode(head, ID);
  Displaystaff(p->Staff);
  break;
 
 case 2:
  printf("===== Please enter the name======\n");
  scanf("%s", name);
  searchnodebyname(head, name);
  break;
 
 case 3:
  flag = 0;
  break;
 }
 system("pause");
 system("cls");
 
 
 }while(flag == 1);
}
