How can I call a function using a function pointer?

Question

Suppose I have these three functions:

bool A();
bool B();
bool C();

How do I call one of these functions conditionally using a function poi

Answer 1

I usually use typedef to do it, but it may be overkill, if you do not have to use the function pointer too often..

//assuming bool is available (where I come from it is an enum)

typedef bool (*pmyfun_t)();

pmyfun_t pMyFun;

pMyFun=A; //pMyFun=&A is actually same

pMyFun();
