C语言实现电影管理系统
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]);
