Higher order callback

[joshiajanimesh]

The existing example of Callback using Function pointer is great for a beginner idea.
My attempt is to build upon it giving more of a real-world example where:

1. function signatures are in .h (header files)
2. typdef is used for function pointer definition
3. main uses a register callback function to pass function pointer to the Callback function

This is evident of the Callback being a higher layer function and it is called by a function in another layer of the program. It does this by pointer to the Callback.
