将STL函数与结构一起使用？

struct Person {
    std::string name;
    int age;
};

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

struct Person {
    std::string name;
    int age;
};

int main() {
    std::vector<Person> people = {
        {"Alice", 25},
        {"Bob", 30},
        {"Charlie", 20}
    };

    // 使用Lambda表达式定义排序规则，按年龄升序排序
    std::sort(people.begin(), people.end(), [](const Person& p1, const Person& p2) {
        return p1.age < p2.age;
    });

    // 输出排序结果
    for (const auto& person : people) {
        std::cout << person.name << ", " << person.age << std::endl;
    }

    return 0;
}
