C语言实现电影管理系统
作者:S_aitama
这篇文章主要为大家详细介绍了C语言实现电影管理系统,文中示例代码介绍的非常详细,具有一定的参考价值,感兴趣的小伙伴们可以参考一下
本文实例为大家分享了C语言实现电影管理系统的具体代码,供大家参考,具体内容如下
文件目录
说明:
- user.txt 储存用户名和密码 空格隔开
- data.txt 单行数据分别为:电影名 评分 场次 时长 展厅号 票价 时间段
场次对应后面有几个时间段

所有文件目录需要自己修改,vs中相对路径从工程文件位置开始,dev从.c文件开始,最好使用绝对定位
部分功能解析
1. 登录系统
开头有简易登录系统,暂时只能保存一位用户注册信息(说不定会完善)
简易密码加密:
printf("请输入密码:"); char c; int i = 0; while ((c = getch()) != '\r') { if (c == '\b') { i--; putchar('\b'); putchar(' '); putchar('\b'); } else { password[i] = c; i++; putchar('*'); } } printf("\n"); password[i] = '\0';
输入密码时用getch()
函数不回显特性,将数据存入c但不显示在窗口,同时putchar(*)
做到视觉加密
遇到退格\b
时,先将光标前移一位,然后用空格代替原本 *,再将光标前移等待下次录入
2. 载入
void Reload() { int number,time,hall,count=0,grade; double price; char name[100]; char timeline[100][100]; List b=head; FILE* p = fopen("data.txt", "a+"); while (fscanf(p, "%s%d%d%d%d%lf",name,&grade,&number,&time,&hall,&price) == 6) { List a = (List)malloc(sizeof(Cinema)); b->next=a; a->grade = grade; a->price = price; a->time = time; a->hall = hall; a->number = number; strcpy(a->name, name); for(int i=0;i<number;i++) { fscanf(p,"%s",timeline[i]); strcpy(a->timeline[i], timeline[i]); } b = b->next; count++; } if(count!=0) b->next = NULL; printf("成功载入%d条信息\n\n", count); fclose(p); }
登录成功后,自动把文件中信息载入内存,同时显示成功载入的信息
3. 时段排版
根据一天上映的场次决定最后时间段展示的行数DisplayAll()
函数中:
for(int i=1;i<a->number;i++) printf("\t\t\t\t\t\t\t\t\t\t\t\t[%d]%s\n",i+1,a->timeline[i]);
