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?
