The example of this paper is to share the implementation code of C++ basic student management system for your reference, the specific content is as follows

Suitable for c++6.0,codeblocks and other common tools

1. Processing part of the linked list


#include<stdio.h>
#include<string.h>
#include<stdlib.h>
 
#include"linklist.h"
#include"elem.h"
 
 
void dispnode(linklist h)
{
 node *p;
 p=h->next;
 while(p)
 {
 dispelem(p);
 p=p->next;
 }
 
}
 
int inputnode(linklist h,T e)
{
 node *p;
 node *q;
 p=h;
 while(p->next&& (p->next->data).id<=e.id)
 {
 if((p->next->data).id==e.id)
  return 0;
 p=p->next;
 }
 q=(node*)malloc(sizeof(node));
 q->data=e;
 q->next=p->next;
 p->next=q;
 return 1;
}
 
int delnode(linklist h,int id)
{
 node *p;
 p=h;
 while(p->next&&(p->next->data).id!=id)
 p=p->next;
 if(p->next)
 {
 node *t=p->next;
 p->next=t->next;
 free(t);
 return 1;
 
 }
 else
 return 0;
 
}
 
node* searchname(linklist h,char name[])
{
 node *p;
 p=h-next;
 while( p && strcmp((p->data).name ,name)!=0)
 p=p->next;
 return p;
}
 
node* searchid(linklist h,int id)
{
 node *p;
 p=h->next;
 while( p->next && (p->next->data).id <= e.id )
 p=p->next;
 return p;
}

2. Data processing section


#include<stdio.h>
#include<string.h>
#include<stdlib.h>
 
#include"linklist.h"
#include"elem.h"
 
 
void dispnode(linklist h)
{
 node *p;
 p=h->next;
 while(p)
 {
 dispelem(p);
 p=p->next;
 }
 
}
 
int inputnode(linklist h,T e)
{
 node *p;
 node *q;
 p=h;
 while(p->next&& (p->next->data).id<=e.id)
 {
 if((p->next->data).id==e.id)
  return 0;
 p=p->next;
 }
 q=(node*)malloc(sizeof(node));
 q->data=e;
 q->next=p->next;
 p->next=q;
 return 1;
}
 
int delnode(linklist h,int id)
{
 node *p;
 p=h;
 while(p->next&&(p->next->data).id!=id)
 p=p->next;
 if(p->next)
 {
 node *t=p->next;
 p->next=t->next;
 free(t);
 return 1;
 
 }
 else
 return 0;
 
 
 
 
}
 
node* searchname(linklist h,char name[])
{
 node *p;
 p=h-next;
 while( p && strcmp((p->data).name ,name)!=0)
 p=p->next;
 return p;
}
 
node* searchid(linklist h,int id)
{
 node *p;
 p=h->next;
 while( p->next && (p->next->data).id <= e.id )
 p=p->next;
 return p;
}

3. Document processing section


#include<stdio.h>
#include<string.h>
#include<stdlib.h>
 
#include"linklist.h"
#include"elem.h"
 
 
void dispnode(linklist h)
{
 node *p;
 p=h->next;
 while(p)
 {
 dispelem(p);
 p=p->next;
 }
 
}
 
int inputnode(linklist h,T e)
{
 node *p;
 node *q;
 p=h;
 while(p->next&& (p->next->data).id<=e.id)
 {
 if((p->next->data).id==e.id)
  return 0;
 p=p->next;
 }
 q=(node*)malloc(sizeof(node));
 q->data=e;
 q->next=p->next;
 p->next=q;
 return 1;
}
 
int delnode(linklist h,int id)
{
 node *p;
 p=h;
 while(p->next&&(p->next->data).id!=id)
 p=p->next;
 if(p->next)
 {
 node *t=p->next;
 p->next=t->next;
 free(t);
 return 1;
 
 }
 else
 return 0;
 
 
 
 
}
 
node* searchname(linklist h,char name[])
{
 node *p;
 p=h-next;
 while( p && strcmp((p->data).name ,name)!=0)
 p=p->next;
 return p;
}
 
node* searchid(linklist h,int id)
{
 node *p;
 p=h->next;
 while( p->next && (p->next->data).id <= e.id )
 p=p->next;
 return p;
}

4. Customize the main menu


#include <stdio.h>
#include <stdlib.h>
 
 
#include "linklist.h"
#include "elem.h"
#include "fileop.h"
 
void mainmenu();
 
void searchlinklist(linlist h)
{
 linklist h;
 h=(linklist)malloc(sizeof(node));
 h->next=NULL;
 loadfile(h);
 mainmenu(h);
 savefile(h);
 printf("\n");
 return 0;
}
void mainmenu()
{
 node *p;
 int id;
 T e;
 int select;
 int count=1;
 do
 {
 printf("\n");
 printf(" ----------------¡¶SSMGS OS¡ ・  ---------------\n");
 printf(" 1 displaying 2 searching 3 adding 4 deleting\n\n");
 printf("   5 changing 6 extiting \n");
 printf(" --------------------welcome ------------------------\n");
 printf("please input your select: ");
 scanf("%d", &select);
 switch(select)
 {
 case 1:
  dispnode(h);
  break;
 case 2:
  searchlinlist(h);
  break;
 case 3:
  inputelem(&e);
  if(inputnode(h,e))
  printf("succeed\n");
  else
  printf("failed\n");
  break;
 case 4:
  printf("please input id:");
  scanf("%d",&id);
 
  break;
 case 5:// Function reference 
  break;
 case 6:// Function reference 
  count=0;
  break;
 }
 
 }while(count);
 
}
