What is callback function C++?
A callback is a callable (see further down) accepted by a class or function, used to customize the current logic depending on that callback. One reason to use callbacks is to write generic code which is independant from the logic in the called function and can be reused with different callbacks.

What is multicast delegate explain with example?
A Multicast Delegate is a delegate that holds the references of more than one function.
