C++ Smart Pointers

Manage memory automatically without manual delete using unique_ptr and shared_ptr.

❮ Previous Next ❯

Modern C++ avoids manual new and delete in favor of smart pointers in <memory>: std::unique_ptr for exclusive ownership, and std::shared_ptr for reference-counted ownership.

Key Takeaways: C++ Smart Pointers

Mastering C++ Smart Pointers helps you write clean and reliable C++ code. Follow standard conventions, test edge cases, and keep logic simple. Try running the code example below and complete the exercises to build confidence.

C++ Smart Pointers Code Example

C++

#include <iostream>
#include <memory>

class Resource {
public:
    Resource() { std::cout << "Resource created\n"; }
    ~Resource() { std::cout << "Resource destroyed\n"; }
};

int main() {
    {
        std::unique_ptr<Resource> ptr = std::make_unique<Resource>();
    } // Automatically freed when out of scope!
    return 0;
}

Output

Resource created
Resource destroyed
