Question

in .

Answer 1

Let's take an example

typedef void (*pt2fn)(int);

Here, we are defining a type pt2fn. Variables of this type point to functions, that take an integer as argument and does not return any value.

pt2fn kk;

Here, kk is a variable of type pt2fn, which can point to any function that takes in an integer as input and does not return any value.
