校友信息管理系统c++

校友信息管理系统是一个比较常见的管理系统，用 C++ 实现也比较方便。下面是一个简单的校友信息管理系统的实现，包括添加、删除、查询和修改校友信息。

#include <iostream>
#include <string>
using namespace std;

const int MAXSIZE = 100; // 最大记录数

// 校友信息结构体
struct Alumni {
    string name;    // 姓名
    string gender;  // 性别
    int age;        // 年龄
    string major;   // 专业
    string company; // 工作单位
};

// 校友信息管理类
class AlumniManagement {
public:
    // 添加一条记录
    void addRecord() {
        if (count >= MAXSIZE) {
            cout << "记录已满，无法添加！" << endl;
            return;
        }
        Alumni alumni;
        cout << "请输入姓名：";
        cin >> alumni.name;
        cout << "请输入性别：";
        cin >> alumni.gender;
        cout << "请输入年龄：";
        cin >> alumni.age;
        cout << "请输入专业：";
        cin >> alumni.major;
        cout << "请输入工作单位：";
        cin >> alumni.company;
        records[count++] = alumni;
        cout << "添加成功！" << endl;
    }

    // 删除一条记录
    void deleteRecord() {
        if (count == 0) {
            cout << "记录为空，无法删除！" << endl;
            return;
        }
        string name;
        cout << "请输入要删除的校友姓名：";
        cin >> name;
        for (int i = 0; i < count; i++) {
            if (records[i].name == name) {
                for (int j = i; j < count - 1; j++) {
                    records[j] = records[j+1];
                }
                count--;
                cout << "删除成功！" << endl;
                return;
            }
        }
        cout << "未找到该校友记录！" << endl;
    }

    // 查询一条记录
    void queryRecord() {
        if (count == 0) {
            cout << "记录为空，无法查询！" << endl;
            return;
        }
        string name;
        cout << "请输入要查询的校友姓名：";
        cin >> name;
        for (int i = 0; i < count; i++) {
            if (records[i].name == name) {
                cout << "姓名：" << records[i].name << endl;
                cout << "性别：" << records[i].gender << endl;
                cout << "年龄：" << records[i].age << endl;
                cout << "专业：" << records[i].major << endl;
                cout << "工作单位：" << records[i].company << endl;
                return;
            }
        }
        cout << "未找到该校友记录！" << endl;
    }

    // 修改一条记录
    void modifyRecord() {
        if (count == 0) {
            cout << "记录为空，无法修改！" << endl;
            return;
        }
        string name;
        cout << "请输入要修改的校友姓名：";
        cin >> name;
        for (int i = 0; i < count; i++) {
            if (records[i].name == name) {
                cout << "请输入新的信息（不输入则不修改）：" << endl;
                cout << "姓名：";
                cin >> records[i].name;
                cout << "性别：";
                cin >> records[i].gender;
                cout << "年龄：";
                cin >> records[i].age;
                cout << "专业：";
                cin >> records[i].major;
                cout << "工作单位：";
                cin >> records[i].company;
                cout << "修改成功！" << endl;
                return;
            }
        }
        cout << "未找到该校友记录！" << endl;
    }

private:
    Alumni records[MAXSIZE]; // 校友信息记录
    int count = 0;           // 当前记录数
};

int main() {
    AlumniManagement management;
    int choice;
    while (true) {
        cout << "1.添加记录" << endl;
        cout << "2.删除记录" << endl;
        cout << "3.查询记录" << endl;
        cout << "4.修改记录" << endl;
        cout << "5.退出程序" << endl;
        cout << "请选择操作：";
        cin >> choice;
        switch (choice) {
            case 1:
                management.addRecord();
                break;
            case 2:
                management.deleteRecord();
                break;
            case 3:
                management.queryRecord();
                break;
            case 4:
                management.modifyRecord();
                break;
            case 5:
                return 0;
            default:
                cout << "无效操作，请重新选择！" << endl;
        }
        cout << endl;
    }
}

以上是一个简单的校友信息管理系统的实现，你可以根据自己的需求进行修改和扩展。
