从std::vector中的每个对象调用重载函数

#include <iostream>
#include <vector>

class Person {
public:
    std::string name;
    int age;

    Person(std::string n, int a) : name(n), age(a) {}
};

void printInfo(const Person& p) {
    std::cout << "Name: " << p.name << ", Age: " << p.age << std::endl;
}

void printInfo(const Person& p, bool detailed) {
    if (detailed) {
        std::cout << "Detailed Info: Name: " << p.name << ", Age: " << p.age << std::endl;
    } else {
        printInfo(p);
    }
}

int main() {
    std::vector<Person> people = { {"Alice", 30}, {"Bob", 25}, {"Charlie", 35} };

    for (const auto& person : people) {
        printInfo(person); // 调用基本信息的重载函数
        printInfo(person, true); // 调用详细信息的重载函数
    }

    return 0;
}

void foo(int x);
void foo(double x);

foo(static_cast<int>(10.0)); // 显式调用 foo(int x)
