C中的函數指針如何工做？ - How do function pointers in C work?

問題：

I had some experience lately with function pointers in C. 我最近對C中的函數指針有一些經驗。

So going on with the tradition of answering your own questions, I decided to make a small summary of the very basics, for those who need a quick dive-in to the subject. 所以，繼續回答您本身的問題的傳統，我決定爲那些須要快速學習該主題的人作一些基本的總結。
