The video tutorial explains the use of smart pointers in C++ and emphasizes avoiding direct use of new and delete operators. It introduces make_unique and make_shared functions for creating unique and shared pointers, respectively, without manual memory allocation. The tutorial highlights the advantages of these functions, such as reducing multiple calls to new and delete, and discusses their limitations, including the inability to specify custom deleters.
