Function pointer is a special type of pointer that is used in order to store the address of a function.
Function pointer syntax is complex and many beginners find it hard to understand.
In this video, I'll explain how to use function pointers in C++ and what is their purpose.
I'll show you how to create a function pointer, how to invoke a function using a function pointer, and also how to use and create function pointers to functions that receive parameters/arguments.
Function pointers are often used in order to optimize the code and make it reusable, and in this video, I'll explain how to use a function pointer in order to pass a function as a parameter/argument to another function.
