C + + to achieve a simple staff management system training Code _c language

Examples of this article for you to share the C + + employee Management System Instance code

1. Single Worker's head document
staff.h

#ifndef staff_h_included #define STAFF_H_INCLUDED//struct body to create struct STAFF {char id[10];
  Char name[10];
  Char sex[10];
  int pay;
  int reward;
int factpay;
};
Custom structural body typedef struct staff staff;
Individual employee information to create staff createstaff ();
Single worker information output void Displaystaff (staff staff);
 
Modify employee information void Updatestaff (staff *staff); #endif//staff_h_included CPP file for individual employees 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 ("-----Show the data to be modified--------\ n");
 
  Displaystaff (*staff);
  printf ("-------Enter the data to be modified---------");
  printf ("-----------pay-----------\ n");
  scanf ("%d", &staff->pay);
  printf ("-----------reward-----------\ n");
  scanf ("%d", &staff->reward);
  Staff->factpay = Staff->pay + staff->reward;
 
printf ("\ n");
 }

2. The creation of the linked list
header file for linked list
Linklist.h

Create struct node #ifndef linklist_h_included #define linklist_h_included
#include "staff.h"
//Linked list node
{
  struct staff staff;
  struct Node *next;
Custom node
 
typedef struct node node;
typedef struct NODE *linklist;
Create a linked list
node *createlinklist ();
Data
void Displaylinklist (node *head) in the output list;
Find employee
Node *searchnode (node *head, Char id[] by employee number;
Find workers by name
void Searchnodebyname (node *head, char name[]);
Delete worker
void Delenode (linklist head, Char id[]);
Insert worker
void Insertnode (linklist Head, staff staff);
Chain list destroys
void Distroylinklist (linklist head);
 
#endif//linklist_h_included

Source program created by linked list
Linklist.cpp

#include <stdio.h> #include <stdlib.h> #include <string.h> #include "staff.h" #include "linklist.h" no
 
  De *createlinklist () {node *head, *p;
  Head = (node *) malloc (sizeof (node));
  Head->next = NULL; Staff a[100] = {"11111", "MMM", "f", 12000, Watts, 14000}, {"22222", "AAA", "M", 13000, 3000, 16000}, {"33 333 "," SSS "," F ", 15000, 3000, 18000}, {" 44444 "," fff "," M ", 17000, 8000, 25000}, {" 55555 "," GGG "," F ", 20
  000, 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&AMP;&AMP;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 disk
file.h

 #ifndef file_h_included #define file_h_included #include "linklist.h" #include "staff.h"/
The worker information is filed void Saveinformation (Linklist head);
 
 
Employee Information loaded 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 is missing or will load test data for First run");
  return;
  while (Fread (&nodebuffer, sizeof (node), 1, FP)!=0) {Insertnode (H, Nodebuffer); }
 
}

4. Main function
mainmeun.cpp

#include <stdio.h> #include <stdlib.h> #include "linklist.h" #include "staff.h" #include "file.h" void Mainme
Un (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 \ nthe");
  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 output =====2. Data Query =====\n");
    printf ("=======3. Data deletion ===4. Data modification =====5. Add Data ======\n");
    printf ("=======6. Linked list destruction ===7. Information save =====8. Discard Disk =====\n");
 
    printf ("==================================================\n");
    printf ("Please select the function (1~8):");
    scanf ("%d", &selection);
   Switch (selection) { Case 1:displaylinklist (head);
    Break
 
      Case 2:searchmenu (head);
    Break
      Case 3:printf ("========= Please enter the work number ==========\n");
      scanf ("%s", ID);
      Delenode (head, ID);
    Break
      Case 4:printf ("========= Please enter the work 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 ("========= lookup 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 id=======\n");
      scanf ("%s", ID);
      p = Searchnode (head, ID);
      Displaystaff (P->staff);
 
    Break
      Case 2:printf ("===== Please enter name======\n");
      scanf ("%s", name);
      Searchnodebyname (head, name);
 
    Break
      Case 3:flag = 0;
    Break
    System ("pause");
 
 
  System ("CLS");
}while (flag = 1); }
