在C++中选择具有指定特征的人员

#include <iostream>
#include <algorithm>
#include <vector>

// 人员类
class Person {
public:
    std::string name;
    int age;
    std::string gender;
    std::string skill;

    Person(std::string name, int age, std::string gender, std::string skill)
        : name(name), age(age), gender(gender), skill(skill) {}
};

// 谓词函数，判断人员是否满足条件
bool isDesiredPerson(const Person& person) {
    // 自定义条件判断逻辑，例如筛选年龄大于等于18岁且具备C++开发技能的人员
    return person.age >= 18 && person.skill == "C++";
}

int main() {
    // 创建人员容器并添加人员
    std::vector<Person> persons;
    persons.push_back(Person("张三", 20, "男", "C++"));
    persons.push_back(Person("李四", 25, "女", "Java"));
    persons.push_back(Person("王五", 30, "男", "Python"));
    persons.push_back(Person("赵六", 22, "女", "C++"));

    // 筛选满足条件的人员
    std::vector<Person> desiredPersons;
    std::copy_if(persons.begin(), persons.end(), std::back_inserter(desiredPersons), isDesiredPerson);

    // 输出结果
    for (const auto& person : desiredPersons) {
        std::cout << "姓名：" << person.name << "，年龄：" << person.age
                  << "，性别：" << person.gender << "，技能：" << person.skill << std::endl;
    }
