Complete Modern C++ - Callbacks Revisited - Function Pointers

The video revisits function pointers and introduces a sorting algorithm using function templates. It discusses the limitations of sorting in ascending order and handling C-style strings. The video then explains how to generalize comparisons using function pointers and predicates, allowing flexible sorting. It highlights the limitations of function pointers, such as lack of optimization and state management, and suggests using function objects as an alternative.
