Complete Modern C++ - Deleter

The video tutorial explains the features of smart pointers, focusing on their default behavior of calling delete, which can lead to undefined behavior when managing resources not acquired with new. It introduces custom deleters, which can be any callable, to manage such resources. The tutorial covers creating custom deleters using function objects, global functions, or lambda expressions, and demonstrates their implementation with unique and shared pointers. It highlights the differences in specifying deleters for these pointers, emphasizing the need to specify the deleter type for unique pointers but not for shared pointers.
