C语言实现影院售票管理系统

typedef struct node
{
  char name[N];       // 名称
  char type[N];       // 类型
  int time;         // 时长
  char day[N];       // 日期
  char start[N];       // 起始时间
  char site[N];       // 地点
  int price;        // 价格
  int num;         // 数量
  int id;          // 编号
  int seat[N][N];      // 座位
  struct node* next;     // 指针域
}NODE;
实现功能：
