用C++编写旅游客户信息管理系统

好的，旅游客户信息管理系统可以包含以下功能：

1. 添加客户信息：包括客户姓名、性别、年龄、联系方式、身份证号等信息。

2. 删除客户信息：根据客户身份证号或者姓名进行删除。

3. 修改客户信息：可以根据客户身份证号或者姓名进行修改客户的信息。

4. 查询客户信息：可以根据客户身份证号或者姓名进行查询客户的信息。

5. 显示客户信息：将所有客户的信息进行显示。

6. 数据存储：将客户信息进行保存，以便下次使用。

在C++中可以使用结构体来存储客户的信息，代码示例：

#include<iostream>
#include<fstream>
#include<cstring>
#include<iomanip>
using namespace std;

struct Customer
{
    char name[20];  // 客户姓名
    char gender[5]; // 客户性别
    int age;        // 客户年龄
    char phone[20]; // 客户联系方式
    char id[20];    // 客户身份证号
};

// 添加客户信息
void addCustomer(Customer customer)
{
    // 将客户信息保存到文件中
    ofstream outFile("customer.txt", ios::app);
    outFile << customer.name << " " << customer.gender << " " << customer.age << " " << customer.phone << " " << customer.id << endl;
    outFile.close();
}

// 删除客户信息
void deleteCustomer(char* id)
{
    ifstream inFile("customer.txt");
    ofstream outFile("temp.txt");
    Customer customer;
    bool found = false;
    while (inFile >> customer.name >> customer.gender >> customer.age >> customer.phone >> customer.id)
    {
        if (strcmp(id, customer.id) == 0)
        {
            found = true;
            continue;
        }
        outFile << customer.name << " " << customer.gender << " " << customer.age << " " << customer.phone << " " << customer.id << endl;
    }
    inFile.close();
    outFile.close();
    remove("customer.txt");
    rename("temp.txt", "customer.txt");
    if (!found)
        cout << "未找到该客户信息！" << endl;
}

// 修改客户信息
void modifyCustomer(char* id)
{
    ifstream inFile("customer.txt");
    ofstream outFile("temp.txt");
    Customer customer;
    bool found = false;
    while (inFile >> customer.name >> customer.gender >> customer.age >> customer.phone >> customer.id)
    {
        if (strcmp(id, customer.id) == 0)
        {
            found = true;
            cout << "请输入客户姓名：";
            cin >> customer.name;

        }
        outFile << customer.name << " " << customer.gender << " " << customer.age << " " << customer.phone << " " << customer.id << endl;
    }
    inFile.close();
    outFile.close();
    remove("customer.txt");
    rename("temp.txt", "customer.txt");
    if (!found)
        cout << "未找到该客户信息！" << endl;
}

// 查询客户信息
void queryCustomer(char* id)
