How does memory management differ between C and C++?
In C, memory management is manual, using functions like malloc and free. C++ offers both manual and automatic management with constructors, destructors, and smart pointers.
What are smart pointers in C++?
Smart pointers are objects that manage memory automatically. They help prevent memory leaks by ensuring that memory is released 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.
When should I use each type of smart pointer?
Use std::unique_ptr for exclusive ownership, std::shared_ptr for shared ownership, and std::weak_ptr to avoid circular references.
