Bug in "Word Counting" Program

I have written a simple program that counts the number of words in the input stream. There is a small bug in the code and i am not able to figure out the cause of this bug.

Code:

#include <stdio.h>
int main()
{
int ichar = 0;
int in_word = 1; 
// in_word = 1 *outside a word* in_word = 0 *inside a word*
int wc = 0;
while((ichar = getchar()) != EOF )
{
    if ((( ichar != ' ' )||(ichar != '\n' )||(ichar !='\t')) && ( in_word == 1 ))
        {
        in_word = 0;
        wc ++ ;
        }
    else if (( ichar == ' ' )||(ichar == '\n' )||(ichar =='\t'))
        {
        in_word = 1;
        }
}
printf ( "Total number of words %d\n" , wc);
return 0;
}

an \n
Whenever i give the above input to the program, (the input contains 2 alphabets a,n then followed by a space and enterkey) the output I get
Total number of words 2

Can someone help me understand why i am getting the output as 2 words?

NAME

       vlatai - Lojban word analyzer

SYNOPSIS

       vlatai [ -v ] [ word ]

DESCRIPTION

       vlatai is a program that reads a list of Lojban words from standard input, one word per line.  In its usual mode, it writes a single output
       line for each input line, advising of which kind of Lojban word the input line is.   If the input word has cmavo prefixed onto  it,  vlatai
       shows the individual cmavo and the base word itself.

       In the verbose mode (obtained using -v), the workings of the internal state machines used for scanning the word are exposed.  This may give
       some insight into where an error lies on words that can't be parsed, especially if the output is used in conjuction with the  report  files
       built during the compilation process.

       Note that vlatai is primarily a testbench for the word categorizer/splitter inside jbofihe.  vlatai is not fully supported or documented as
       a stand-alone program.

OPTIONS

       -v     Verbose; show lots of information about the evolution of the internal state

       word   The word to check.  If no 'word' argument is supplied, the program reads words from standard input,  one	word  per  line  (with	no
	      whitespace around it.)
