Smart Pointers with std::shared_ptr

This example shows how to use std::shared_ptr for shared ownership of dynamically allocated objects.

cppCopy code#include <iostream>
#include <memory>

class Resource {
public:
    Resource() { std::cout << "Resource acquired." << std::endl; }
    ~Resource() { std::cout << "Resource released." << std::endl; }
};

int main() {
    std::shared_ptr<Resource> res1 = std::make_shared<Resource>();
    {
        std::shared_ptr<Resource> res2 = res1; // Shared ownership
        std::cout << "Inside the block." << std::endl;
    } // res2 goes out of scope, but res1 still holds the resource

    std::cout << "Exiting main." << std::endl;
    return 0;
}
