The function pointer must have a return type and parameters that match the function it is referencing. And just as with data pointers, we use the asterisk * to declare the pointer.

And by that logic, if we can do something like some_function(&regular_variable) in C, i.e. pass a pointer as parameter to a function, we should be able to do the same with registers.

Delegates are type safe function pointers *with an optional this pointer* thus no need to pass one round yourself. Obviously their utility is much enhanced in contract to C++ by virtue of being ...

Passing a function into a function is a perfectly legal (and extremely useful) thing to do in C++. Check the index of your book for "function pointers" or "pointers to functions" and see what you ...
