    Counting specific word from file

    The task that i'm trying to perform is to count the number of times that an specific word is repeated on a .txt file. In this case the word "the".

    My first attempt is:
    Code:
    while(*bufptr++ != '\0'){
        if(strncmp (bufptr,"the",3) == 0){
        i++;
        }}
        printf("The word THE was writen %d times on the file\n",i);
    where bufptr is a pointer to memory: char *bufptr;

    The problem is that with that code it counts not only "the" but also words such as "theater", "lathe". How can i narrow the counting to only count "the" words?.

    Thanks in advance.

    how about if(strncmp (bufptr,"the ",4) == 0)/? Notice the space after the 'e' in "the".

    thanks, with your advice i narrowed to not count words like "theater", then i modified to if(strncmp (bufptr," the ",5) == 0) for "lathe" likes.

    Only problem you might run into is if the first word of the text file is "The". Then you might be down one count of "the".

    That's what i've noticed so far, i think that by doing a OR check during the if it can be solved

    No, that's still going to reject a lot of valid strings. Just verify that the very next character isn't alphabetical and everything should work fine.
