/************************************************
I used dmc for this, "dmc whatever.c", but most
other C compilers should also work

Declares a 'thestruct' struct and associates a function
with the instance. The function simply returns the
number 2 and the main program prints out that integer
*************************************************/

#include <stdio.h>

typedef struct {

 int (* something)(); // pointer to function declared like this,
                      // return_type (* func_name)(arguments)
                      // this will be your object's behavior

} thestruct;


int func() // just does something useless, like return a constant
{
  return 2;
}


void main()
{

 thestruct a;  // declare thestruct
 a.something = func; // associate the function 'func' with the emulated behavior
                     // named 'something'

 printf("%d\n", a.something()); // call the behavior, like in C++
