pointers

Hi, I have trouble seing the utility of the function pointers. I guess it may be useful in some case (it exists, after all), but I can't think of a case where it's better or unavoidable to use a function pointer.

Could you give some example of good use of function pointers (in C or C++)?

Many thanks :)
