Function Pointer – Automatic Dereferencing [duplicate]

This is just a quirk of C. There’s no other reason but the C standard just says that dereferencing or taking the address of a function just evaluates to a pointer to that function, and dereferencing a function pointer just evaluates back to the function pointer.

This behavior is (thus obviously) very different from how the unary & and * operators works for normal variables.

So,

test2 = myprint;
test2 = &myprint;
test2 = *myprint;
test2 = **********myprint;

All just do exactly the same, gives you a function pointer to myprint

Similarly,

test2(s);
(*test2)(s);
(***********test2)(s);

Does the same, call the function pointer stored in test2. Because C says it does.
