Example: Operator Overloading Example in C++

// Operator Overloading Example
#include <iostream>
#include <string>

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

    Person(std::string n = "Unknown", int a = 0) : name(n), age(a) {}

    // Friend function to overload << for output
    friend std::ostream& operator<<(std::ostream& os, const Person& p) {
        os << "Name: " << p.name << ", Age: " << p.age;
        return os;
    }

    // Friend function to overload >> for input
    friend std::istream& operator>>(std::istream& is, Person& p) {
        std::cout << "Enter person's name: ";
        is >> p.name;
        std::cout << "Enter person's age: ";
        is >> p.age;
        return is;
    }
};

int main() {
    Person p1("John Doe", 25);
    Person p2; // Default constructor

    // Using overloaded << to print
    std::cout << "Person 1 details: " << p1 << std::endl;

    // Using overloaded >> to read input
    std::cout << "\nEnter details for Person 2:\n";
    std::cin >> p2;

    // Using overloaded << to print Person 2
    std::cout << "\nPerson 2 details: " << p2 << std::endl;

    return 0;
