学生信息管理系统c++代码

以下是一个简单的学生信息管理系统的C++代码示例：

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

struct Student {
    string name;
    int age;
    string major;
};

void addStudent(Student students[], int& count) {
    cout << "请输入学生姓名：";
    cin >> students[count].name;
    cout << "请输入学生年龄：";
    cin >> students[count].age;
    cout << "请输入学生专业：";
    cin >> students[count].major;
    count++;
}

void displayStudents(Student students[], int count) {
    cout << "学生信息如下：" << endl;
    for (int i = 0; i < count; i++) {
        cout << "姓名：" << students[i].name << endl;
        cout << "年龄：" << students[i].age << endl;
        cout << "专业：" << students[i].major << endl;
        cout << endl;
    }
}

int main() {
    const int MAX_STUDENTS = 100;
    Student students[MAX_STUDENTS];
    int count = 0;
    char choice;

    do {
        cout << "请选择操作：" << endl;
        cout << "1. 添加学生信息" << endl;
        cout << "2. 显示学生信息" << endl;
        cout << "0. 退出程序" << endl;
        cout << "请输入选项：";
        cin >> choice;

        switch (choice) {
            case '1':
                addStudent(students, count);
                break;
            case '2':
                displayStudents(students, count);
                break;
            case '0':
                cout << "程序已退出。" << endl;
                break;
            default:
                cout << "无效的选项，请重新输入。" << endl;
                break;
        }
    } while (choice != '0');

    return 0;
}
