How can I prevent memory leaks in C++ and Java?

To prevent memory leaks in C++, ensure you properly manage memory with smart pointers and always delete allocated memory. In Java, use garbage collection effectively and avoid unnecessary object creation.

What are smart pointers in C++?

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

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 in memory management.

How does garbage collection work in Java?

Garbage collection in Java automatically identifies and disposes of objects that are no longer in use, freeing up memory and preventing leaks.
