I try to change the code from while(..) to do{.. } while(..) .. it works..
do
{
c[0]=fgetc(fin); // get each character from inputfile
write(fd[1],c,2); // write to pipe
}
while(c[0]!=EOF)
and it's work.. but wrong result.. Because the last c[0] = EOF, it is written to pipe, then while loop check the codition.. ( wrong ofcourse)..
I include if statement like this:
if(c[0]!= EOF)
{
c[0]=fgetc(fin);// get each character from inputfile
write(fd[1],c,2); // write to pipe
}
Problem again.. The output is blank.. so crazy.. please help me..

ungetc
GETS(3) Linux Programmer's Manual GETS(3)
NAME
fgetc, fgets, getc, getchar, gets, ungetc - input of characters and strings
SYNOPSIS
#include <stdio.h>
int fgetc(FILE *stream);
char *fgets(char *s, int size, FILE *stream);
int getc(FILE *stream);
int getchar(void);
char *gets(char *s);
int ungetc(int c, FILE *stream);
DESCRIPTION
fgetc() reads the next character from stream and returns it as an unsigned char cast to an int, or EOF on end of file or error.
getc() is equivalent to fgetc() except that it may be implemented as a macro which evaluates stream more than once.
getchar() is equivalent to getc(stdin).
gets() reads a line from stdin into the buffer pointed to by s until either a terminating newline or EOF, which it replaces with '
