Question

What is a pointer to a function? Give the general syntax for the same in C Programming?

Answer 1

A pointer holding the reference of the function is called pointer to a function. In general it is declared as follows.

T (*fun_ptr) (T1,T2…); Where T is any date type.

Once fun_ptr refers a function the same can be invoked using the pointer as follows.

fun_ptr();

[Or]

(*fun_ptr)();
