用C++咋写呀,我写的都不对

#include <iostream>
#include <string>

struct Student {
    std::string name;
    int age;
    std::string gender;
};

int main() {
    const int numStudents = 4;  // 学生数量

    Student students[numStudents];  // 存储学生信息的数组

    // 输入学生信息
    for (int i = 0; i < numStudents; ++i) {
        std::cout << "请输入第 " << i+1 << " 个学生的姓名：";
        std::getline(std::cin, students[i].name);
        std::cout << "请输入第 " << i+1 << " 个学生的年龄：";
        std::cin >> students[i].age;
        std::cout << "请输入第 " << i+1 << " 个学生的性别：";
        std::cin >> students[i].gender;
        std::cin.ignore();  // 忽略输入缓冲区的换行符
    }

    // 输出学生信息
    std::cout << "学生信息如下：" << std::endl;
    for (int i = 0; i < numStudents; ++i) {
        std::cout << "姓名：" << students[i].name << std::endl;
        std::cout << "年龄：" << students[i].age << std::endl;
        std::cout << "性别：" << students[i].gender << std::endl;
    }

    return 0;
}
