Odd field in struct? c++ -



Odd field in struct? c++ -

hi wondering if explain me field in struct looks this:

struct illustration { void (someclass::*somemethod)(); };

we set pointer address of actual function , execute function via pointer time later. function pointers convenient thing providing different functions handle task depending on circumstances.

c++
