Preface

Recently, I happened to be writing my own curriculum , The lesson design system written in a hurry , There are still shortcomings , Take it out and share it with you , I hope it can help you .

One 、 Outline design

1、 essential information

data type ： Linked list 

typedef struct node
{
    
    char name[N];          		//  name 
    char type[N];          		//  type 
    int time;              		//  Duration 
    char day[N];            	//  date 
    char start[N];         		//  Starting time 
    char site[N];           	//  place 
    int price;              	//  Price 
    int num;                	//  Number 
    int id;                 	//  Number 
    int seat[N][N];       		//  seat 
    struct node* next;       	//  Pointer to the domain 
}NODE;

Realization function ：

typedef struct ticket
{
    
    char name[N];           	//  name 
    char type[N];           	//  type 
    int time;              		//  Duration 
    char day[N];            	//  date 
    char start[N];          	//  Starting time 
    char site[N];           	//  place 
    int price;             		//  Price 
    int id;                   	//  Number 
    char username[N];        	//  user name 
    int x;                		//  That's ok 
    int y;               	 	//  Column 
    int istake;                	//  Whether to collect tickets 
    struct ticket* next;      	//  Pointer to the domain
