Dev - C++ - Ayudar a que compile, que me falta?

#include <stdio.h>

#include <stdlib.h>

#include <cstdio>

#define  CKPSENSOR 9

#define	 GROUND    realy?

#define  LEDUP     0

#define  LEDDOWN   1

#define  RPMMAX    3200

#define  RPMMIN    1000

const:

	CKPSENSOR  PIN9

	GROUND     realy?

    LEDUP      PIN0

    LEDDOWN    PIN1

    RPMMAX     3200 (it's RPM to proced to set ON the "LEDUP")

    RPMMIN     1000 

var:

	pastPulse =0 (save on this variable the past pulse value)

	actualPulse=0 (obtaning this from read an arduino port)

	actualRPM (obtain this from calculate many things)

	readingTime (count the time for every seconds count 

	             actualRPM)

**principal looping process (principal function)

  chekIfTimeHappened(readingTime)

  if false (actual time is not completed)

      actualPulse = readArduinoPort (port = CKPSENSOR)

      compare (pastPulse & actualPulse)

      if diferent

        actual RPM= (actualRPM + 1)

      if equals

         nothing XD

  if true

      chek RPM> PRMMAX

	  if true

	     turnOnArduinoPort(LEDUP)
