What is garbage collection in C++?

What is garbage collection in C++?

Garbage collection in C++ refers to the automatic memory management feature that helps in reclaiming memory that is no longer in use.

How does it differ from manual memory management?

In manual memory management, the programmer is responsible for allocating and deallocating memory using operators like new and delete. In contrast, garbage collection automates this process.

Does C++ have built-in garbage collection?

C++ does not have built-in garbage collection like some other languages. However, smart pointers (like std::shared_ptr and std::unique_ptr) can help manage memory automatically.

What are smart pointers?

Smart pointers are wrapper classes that manage the lifetime of dynamically allocated objects, ensuring proper memory deallocation.
