#include <stdio.h>
#include <stdlib.h>
/* declare the Point type */
typedef struct
{
  int x, y;
} Point;

/* function to print a Point */
void printPoint( Point *p )
{
  printf("(%d, %d)\n", p->x, p->y );
}

int main()
{
  /* declare and initialize a Point */
  Point point = {123, 456};

  /* print values */
  printPoint( &point );

  return 0;
}
