Visual C++ C1010 unexpected end of file while looking for precompiled header directive

Hi,
     I am a new bee to Visual C++, I have some problem.

This is my main program
----------------------------------------------------------------------------------------
#include "stdafx.h"
#include "parse.h"

int main(int argc, char* argv[])
{
      char first[100],second[100];
      first[0] = '\0',second[0]='\0';
      //second = new char[10];
      printf("Enter the string\n");
      scanf("%s",first);
      printf("The length of the string %s is %d\n",second,strlen(second));
      printf("The concatenated string is %s\n",concatenateN(first,6));
      return 0;
}
----------------------------------------------------------------------------------------
the declaration of concatenateN function is present in the include file parse.h

               parse.h
---------------------------------------------------------------
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <errno.h>
#include <assert.h>
#include <ctype.h>

char *concatenateN(char *,int );
----------------------------------------------------------------

the definition of the function is in parse.c
            parse.c
--------------------------------------------------------------
#include "parse.h"

char *concatenateN(char *str,int n)
{
      char *result = new char[strlen(str)*n+1];
      result[0] = '\0';
      for(int i=0;i<n;i++)
            result = strcat(result,str);
      return result;
}
--------------------------------------------------------------

When I compile this function I am getting the error:
parse.c(15) : fatal error C1010: unexpected end of file while looking for precompiled header directive
Error executing cl.exe.


Then I have included the file stdafx.h in parse.c, which changes the parse.c to

-------------------------------------------------------------
#include "parse.h"

char *concatenateN(char *str,int n)
{
      char *result = new char[strlen(str)*n+1];
      result[0] = '\0';
      for(int i=0;i<n;i++)
            result = strcat(result,str);
      return result;
}

#include <stdafx.h>
-------------------------------------------------------------
Now it is giving the error:
parse.c(14) : fatal error C1853: 'Debug/robots_parse.pch' is not a precompiled header file created with this compiler
Error executing cl.exe.

I searched in MSDN help, but am not able to understand it.

Thanks,
Dp
