在C++中向结构数组添加新项

#include <iostream>
#include <vector>

// 定义结构体
struct Student {
    std::string name;
    int age;
    float score;
};

int main() {
    // 创建一个Student类型的vector
    std::vector<Student> students;

    // 添加新项
    Student newStudent = {"Alice", 20, 95.5};
    students.push_back(newStudent);

    // 输出所有学生信息
    for (const auto& student : students) {
        std::cout << "Name: " << student.name << ", Age: " << student.age << ", Score: " << student.score << std::endl;
    }

    return 0;
}

// 线性搜索示例
Student searchStudent(const std::vector<Student>& students, const std::string& name) {
    for (const auto& student : students) {
        if (student.name == name) {
            return student;
        }
    }
    return {"", -1, -1}; // 返回一个无效的学生信息表示未找到
}

// 删除特定学生信息
void removeStudent(std::vector<Student>& students, const std::string& name) {
    for (auto it = students.begin(); it != students.end(); ++it) {
        if (it->name == name) {
            students.erase(it);
            break;
        }
    }
}
