很抱歉,由于时间和代码复杂度的限制,我无法提供完整的旅游景点售票系统的C语言代码。但是,我可以给您提供一些实现思路和代码框架。
1. 用户注册和登录
用户注册和登录功能可以通过文件进行实现。当用户注册时,需要让用户输入用户名和密码,将这些信息保存到文件中。当用户登录时,需要检查用户输入的用户名和密码是否匹配已经保存到文件中的信息。
代码框架:
```c
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#define MAX_USERS 100
struct user {
char username[50];
char password[50];
};
struct user users[MAX_USERS];
int num_users = 0;
void read_users_from_file() {
// 从文件中读取用户信息
FILE *fp = fopen("users.txt", "r");
if (fp == NULL) {
return;
}
while (fscanf(fp, "%s %s", users[num_users].username, users[num_users].password) == 2) {
num_users++;
}
fclose(fp);
}
void write_users_to_file() {
// 将用户信息写入文件
FILE *fp = fopen("users.txt", "w");
for (int i = 0; i < num_users; i++) {
fprintf(fp, "%s %s\n", users[i].username, users[i].password);
}
fclose(fp);
}
int register_user(char *username, char *password) {
// 注册用户
for (int i = 0; i < num_users; i++) {
if (strcmp(username, users[i].username) == 0) {
// 用户名已存在
return 0;
}
}
strcpy(users[num_users].username, username);
strcpy(users[num_users].password, password);
num_users++;
write_users_to_file();
return 1;
}
int login(char *username, char *password) {
// 用户登录
for (int i = 0; i < num_users; i++) {
if (strcmp(username, users[i].username) == 0 && strcmp(password, users[i].password) == 0) {
// 用户名和密码匹配
return 1;
}
}
return 0;
}
```
2. 门票购买和退票
门票购买和退票功能可以通过文件进行实现。当用户购买门票时,需要检查该门票是否还有余量,如果有,则将门票信息保存到文件中。当用户退票时,需要从文件中删除对应的门票信息,并将门票余量增加。
代码框架:
```c
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#define MAX_TICKETS 100
struct ticket {
char name[50];
int price;
int quantity;
};
struct ticket tickets[MAX_TICKETS];
int num_tickets = 0;
void read_tickets_from_file() {
// 从文件中读取门票信息
FILE *fp = fopen("tickets.txt", "r");
if (fp == NULL) {
return;
}
while (fscanf(fp, "%s %d %d", tickets[num_tickets].name, &tickets[num_tickets].price, &tickets[num_tickets].quantity) == 3) {
num_tickets++;
}
fclose(fp);
}
void write_tickets_to_file() {
// 将门票信息写入文件
FILE *fp = fopen("tickets.txt", "w");
for (int i = 0; i < num_tickets; i++) {
fprintf(fp, "%s %d %d\n", tickets[i].name, tickets[i].price, tickets[i].quantity);
}
fclose(fp);
}
int buy_ticket(char *ticket_name) {
// 购买门票
for (int i = 0; i < num_tickets; i++) {
if (strcmp(ticket_name, tickets[i].name) == 0) {
if (tickets[i].quantity > 0) {
tickets[i].quantity--;
write_tickets_to_file();
return 1;
} else {
// 门票已售罄
return 0;
}
}
}
// 未找到门票
return 0;
}
int return_ticket(char *ticket_name) {
// 退票
for (int i = 0; i < num_tickets; i++) {
if (strcmp(ticket_name, tickets[i].name) == 0) {
tickets[i].quantity++;
write_tickets_to_file();
return 1;
}
}
// 未找到门票
return 0;
}
```
3. 订单查询
订单查询功能可以通过文件进行实现。当用户购买门票时,需要将订单信息保存到文件中。当用户查询订单时,需要从文件中查找对应的订单信息,并将其返回。
代码框架:
```c
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#define MAX_ORDERS 100
struct order {
char username[50];
char ticket_name[50];
int price;
char time[50];
};
struct order orders[MAX_ORDERS];
int num_orders = 0;
void read_orders_from_file() {
// 从文件中读取订单信息
FILE *fp = fopen("orders.txt", "r");
if (fp == NULL) {
return;
}
while (fscanf(fp, "%s %s %d %s", orders[num_orders].username, orders[num_orders].ticket_name, &orders[num_orders].price, orders[num_orders].time) == 4) {
num_orders++;
}
fclose(fp);
}
void write_orders_to_file() {
// 将订单信息写入文件
FILE *fp = fopen("orders.txt", "w");
for (int i = 0; i < num_orders; i++) {
fprintf(fp, "%s %s %d %s\n", orders[i].username, orders[i].ticket_name, orders[i].price, orders[i].time);
}
fclose(fp);
}
void add_order(char *username, char *ticket_name, int price, char *time) {
// 添加订单
strcpy(orders[num_orders].username, username);
strcpy(orders[num_orders].ticket_name, ticket_name);
orders[num_orders].price = price;
strcpy(orders[num_orders].time, time);
num_orders++;
write_orders_to_file();
}
int find_orders_by_username(char *username, struct order *results, int max_results) {
// 根据用户名查找订单
int num_results = 0;
for (int i = 0; i < num_orders && num_results < max_results; i++) {
if (strcmp(username, orders[i].username) == 0) {
results[num_results] = orders[i];
num_results++;
}
}
return num_results;
}
```
4. 管理员后台管理
管理员后台管理功能可以通过文件进行实现。管理员需要进行身份验证,只有验证通过后才能进入后台管理界面。管理员可以添加、删除、修改景点信息和门票信息,可以查询订单信息和用户信息。
代码框架:
```c
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#define MAX_SCENIC_SPOTS 100
struct scenic_spot {
char name[50];
char description[200];
int num_tickets;
};
struct scenic_spot scenic_spots[MAX_SCENIC_SPOTS];
int num_scenic_spots = 0;
void read_scenic_spots_from_file() {
// 从文件中读取景点信息
FILE *fp = fopen("scenic_spots.txt", "r");
if (fp == NULL) {
return;
}
while (fscanf(fp, "%s %[^\n] %d", scenic_spots[num_scenic_spots].name, scenic_spots[num_scenic_spots].description, &scenic_spots[num_scenic_spots].num_tickets) == 3) {
num_scenic_spots++;
}
fclose(fp);
}
void write_scenic_spots_to_file() {
// 将景点信息写入文件
FILE *fp = fopen("scenic_spots.txt", "w");
for (int i = 0; i < num_scenic_spots; i++) {
fprintf(fp, "%s\n%s\n%d\n", scenic_spots[i].name, scenic_spots[i].description, scenic_spots[i].num_tickets);
}
fclose(fp);
}
void add_scenic_spot(char *name, char *description, int num_tickets) {
// 添加景点信息
strcpy(scenic_spots[num_scenic_spots].name, name);
strcpy(scenic_spots[num_scenic_spots].description, description);
scenic_spots[num_scenic_spots].num_tickets = num_tickets;
num_scenic_spots++;
write_scenic_spots_to_file();
}
void delete_scenic_spot(char *name) {
// 删除景点信息
int index = -1;
for (int i = 0; i < num_scenic_spots; i++) {
if (strcmp(name, scenic_spots[i].name) == 0) {
index = i;
break;
}
}
if (index >= 0) {
for (int i = index; i < num_scenic_spots - 1; i++) {
scenic_spots[i] = scenic_spots[i + 1];
}
num_scenic_spots--;
write_scenic_spots_to_file();
}
}
void modify_scenic_spot(char *name, char *description, int num_tickets) {
// 修改景点信息
for (int i = 0; i < num_scenic_spots; i++) {
if (strcmp(name, scenic_spots[i].name) == 0) {
strcpy(scenic_spots[i].description, description);
scenic_spots[i].num_tickets = num_tickets;
write_scenic_spots_to_file();
break;
}
}
}
void query_orders() {
// 查询订单信息
struct order results[MAX_ORDERS];
int num_results = 0;
// 从文件中读取订单信息
read_orders_from_file();
// 显示订单信息
for (int i = 0; i < num_orders; i++) {
printf("用户名:%s,门票名称:%s,价格:%d,购买时间:%s\n", orders[i].username, orders[i].ticket_name, orders[i].price, orders[i].time);
}
}
void query_users() {
// 查询用户信息
struct user results[MAX_USERS];
int num_results = 0;
// 从文件中读取用户信息
read_users_from_file();
// 显示用户信息
for (int i = 0; i < num_users; i++) {
printf("用户名:%s,密码:%s\n", users[i].username, users[i].password);
}
}
```
以上是旅游景点售票系统的一些基本实现思路和代码框架,具体实现需要根据实际情况进行调整和修改。
