Why is my program printing out more times than expected?

Question

I have a program that reads in a file, goes through line by line, and breaks up the line word by word. My problem is, I am about to store each word in a array but I need to use strcmp function to verify the word doesnt already exist. Anyways below is my code and my question is, why is my program printing out 1 so many times? I was expecting it to only print it out twice because this occurs twice in my text file.

while (fgets(line, sizeof(line), fi) != NULL) { // looping through each line

    line_count += 1;

    for (j = 0; j < sizeof(line); j++) { // convert all words to lowercase
        line[j] = tolower(line[j]);
    }

    result = strtok(line, delimiters);

    while (result != NULL) {
        word_count += 1;

        if (strcmp(result, "this")) {
            printf("1\n");
        }

        result = strtok(NULL, delimiters); // get the next token
    }
}

Below is my text file:

This is the first test.

strcmp() returns 0 if the string matches. You're checking for a truthy value. You really want strcmp(result, "this") == 0.

You will also need to make the match case insensitive, which is usually called stricmp().
