hi,

i am a new bie to c programming.

when i am trying to execute one c program,some header files are accessible,while some others are not accessible.

for example


#include <stdlib.h>
#include "../toolkit.h"
#include "../ngram.h"
#include "../evallm.h"
#include "../idngram2lm.h"
the first four header files are accessible,the fifth one is in the same location,but while executing results the following error.

UNABLE TO OPEN INCLUDED FILE '../idngram2lm.h'

the header file is in the same location of the other four header files.Is this due to anything wrong with the header file ?
please guide me
how can i resolve this issue?
