Smart Pointers in C++

This lecture introduces smart pointers in C++11 as a solution to manage dynamic memory allocation efficiently and prevent memory leaks. Smart pointers, including unique_ptr, shared_ptr, and weak_ptr, automatically handle memory deallocation, avoiding the need for manual deletion. The unique_ptr type ensures single ownership of memory, preventing confusion and allowing easy transfer of ownership. Examples demonstrate the usage of unique_ptr, such as creating and accessing dynamic memory objects. Additionally, shared_ptr is discussed for scenarios where memory is shared among multiple parts of the code, while weak_ptr is useful for breaking reference cycles. The lecture emphasizes the importance of smart pointers in modern C++ programming for safer and more reliable memory management.
