Not able to figure out the logical error in C program

A program that prints its input one word per line.

int main() {

    int c;

    while ((c=getchar()) != EOF) {

        if (c== ' ' || c== '\n' ||c == '\t')
                putchar('\n');
        else {
            putchar(c);
        }
    }
    return 0;
}

The above program prints the result correctly, one word per line. After changing the condition accordingly, I was expecting the program below to also print one word per line. However I am not getting the correct result. Am I making some silly mistake or is something wrong?

int main() {

    int c;

    while ((c=getchar()) != EOF) {

        if (c != ' ' || c != '\n' || c != '\t')
            putchar(c);
        else {
            putchar('\n');
        }
    }

    return 0;

}
