用c语言设计程序模拟电影院售票系统

Question

已知某电影院有5个放映厅，请模拟实现电影放映排片和观众购票。系统要求对文件中所存储的票务信息进行各种常规操作，如：查询、计算、显示等功能。通过此课题，熟练掌握文件、数组、指针的各种操作，以及一些算法思想的应用。

我帮你写了一个代码，但是总觉得在c语言中太麻烦了，不如用c++加一个后台数据库存储影片记录：

#include <stdio.h>
#include <string.h>

#define MAX_USER 100
#define MAX_ROOM 5
#define ROW 10
#define COL 10

struct user {
    char username[20];
    char password[20];
};

struct movie {
    char name[50];
    char date[20];
    char time[20];
    int adult_price;
    int child_price;
    int adult_num[ROW][COL];
    int child_num[ROW][COL];
};

struct user users[MAX_USER];
struct movie movies[MAX_ROOM];

void init_users() {
    for (int i = 0; i < MAX_USER; i++) {
        strcpy(users[i].username, "");
        strcpy(users[i].password, "");
    }
}

void init_movies() {
    for (int i = 0; i < MAX_ROOM; i++) {
        strcpy(movies[i].name, "");
        strcpy(movies[i].date, "");
        strcpy(movies[i].time, "");
        movies[i].adult_price = 0;
        movies[i].child_price = 0;

        for (int j = 0; j < ROW; j++) {
            for (int k = 0; k < COL; k++) {
                movies[i].adult_num[j][k] = 0;
                movies[i].child_num[j][k] = 0;
            }
        }
    }
}

int find_user(char* username) {
    for (int i = 0; i < MAX_USER; i++) {
        if (strcmp(users[i].username, username) == 0) {
            return i;
        }
    }

    return -1;
}

int register_user() {
    char username[20], password[20];
    int i;

    printf("请输入用户名：");
    scanf("%s", username);

    i = find_user(username);

    if (i != -1) {
        printf("用户名已存在，请重新输入！\n");
        return 0;
    }

    for (i = 0; i < MAX_USER; i++) {
        if (strcmp(users[i].username, "") == 0) {
            strcpy(users[i].username, username);
            printf("请输入密码：");
            scanf("%s", password);
            strcpy(users[i].password, password);
            printf("注册成功！\n");
            return 1;
        }
    }

    printf("用户数量已达到上限，无法注册！\n");
    return 0;

int login() {
