What is the problem in my question to make it as negative??? — Renjith G, Sep 26 '10 at 07:53
It's way too broad for good specific answers. You're asking for 4 different points here. — BoltClock, Sep 26 '10 at 07:55
There already exists a question that answers what you're asking: http://stackoverflow.com/questions/840501/how-do-function-pointers-in-c-work — Nick Presta, Sep 26 '10 at 07:56
but at least you can mark it as ZERO(0) instead of negative as my question is not at all offensive one right? — Renjith G, Sep 26 '10 at 08:07

Function Pointers are pointers, that is variables, which point to the address of a function.

Nice example here. Also this answer is a must read.

I don't think they point to the address of a function so much as they are the address of a function. – GManNickG Sep 26 '10 at 08:00
