Function pointer in practice

[Kittu20]

Hello Everyone

I understand that function pointer is pointer in c language – that they store the address of a function, they can be use in call back. We can call the function using pointer insted of function name but the question what's advantage of using function pointer instead of using function name

Could you please provide some clarity on why and when function pointers are commonly used ? I'd appreciate any i examples you could offer to help me grasp their usefulness.

Call-back function is one of many cases where the address of a function to be called isn't known at compile time of the calling code. Therefore it can't be statically linked but must be provided as a pointer.
