Function Pointer Question

[Nicholas Krause]

Greetings All, 
I'm a little rough with how function pointers work in C. I assumed there similar to way C++ stores virtual functions internally in  the vtable for virtual functions  by the compiler and checks the table at runtime. Please let me know if I'm wrong in my understanding. 
Thanks, 
Nick
