What are the key features of memory management in C++11?
C++11 introduced several features for better memory management, including smart pointers, which help manage resource lifetimes.
Can you explain how smart pointers work?
Sure! Smart pointers like std::unique_ptr
and std::shared_ptr
automatically manage memory, reducing the risk of leaks.
What is the difference between unique_ptr
and shared_ptr
?
std::unique_ptr
allows only one owner of the resource, while std::shared_ptr
allows multiple owners with reference counting.
Are there any performance implications when using smart pointers?
Yes, shared_ptr
has overhead due to reference counting, while unique_ptr
is lightweight and has minimal overhead.
