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.

What are the potential issues when using smart pointers with resources that cannot be released using delete?

What happens if a smart pointer's deleter does not match the resource management requirements?

Describe the role of a deleter in the context of smart pointers.

Explain how a custom deleter can be specified for a smart pointer.

How can function objects be utilized as custom deleters for smart pointers?

In what scenarios would you prefer using a function object over a function pointer as a deleter?

What is the difference between using a unique pointer and a shared pointer in terms of specifying deleters?
