C++结构集无法按元素查找/擦除

#include <iostream>
#include <vector>

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

int main() {
    std::vector<Person> personList;

    // 添加一些示例数据
    personList.push_back({"Alice", 25});
    personList.push_back({"Bob", 30});
    personList.push_back({"Charlie", 35});

    // 按元素查找
    std::string targetName = "Bob";
    for (auto it = personList.begin(); it != personList.end(); ++it) {
        if (it->name == targetName) {
            std::cout << "找到了目标元素：" << it->name << std::endl;
            break;
        }
    }

    // 按元素擦除
    targetName = "Charlie";
    for (auto it = personList.begin(); it != personList.end(); ++it) {
        if (it->name == targetName) {
            personList.erase(it);
            std::cout << "已擦除目标元素：" << targetName << std::endl;
            break;
        }
    }

    // 输出剩余的元素
    std::cout << "剩余的元素：" << std::endl;
    for (const auto& person : personList) {
        std::cout << person.name << ", " << person.age << std::endl;
    }

    return 0;
