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.

What is the purpose of using function pointers in sorting algorithms?

Explain how a comparator function is used in the sorting process.

What is a predicate in the context of sorting algorithms?

How can you sort an array in descending order using function pointers?

Why can't function pointers be optimized by the compiler?

What are the limitations of using function pointers in sorting algorithms?

Discuss the difference between using function pointers and function objects for callbacks.
