How can I prevent memory leaks in C++?

To prevent memory leaks in C++, you should always ensure that every new has a corresponding delete. Additionally, consider using smart pointers.

What are smart pointers?

Smart pointers are objects that manage the lifetime of dynamically allocated memory. They automatically deallocate memory when it's no longer needed.

Can you give examples of smart pointers?

Sure! The most common smart pointers in C++ are std::unique_ptr, std::shared_ptr, and std::weak_ptr. Each serves different purposes.

How do I use std::unique_ptr?

You can use std::unique_ptr by including the header <memory>. It ensures that only one unique_ptr can own a resource at a time.
