Thread: Getting the last word from a string using strtok?

I'm trying to get the last word from each line in a file using strtok(). I know how to step through each line in the file but I am having trouble getting the last word of the line.

The line looks like this:

Code:

ROOM NAME: Room

so far I have this:

Code:

char *token = strtok(line, " ");
while (token != NULL)
{
printf("%s\n", token);
token = strtok(NULL, " ");
}

The output:

Code:

ROOM
NAME:
Room

I'm printing out each word to see what I'm doing. Ultimately I would like to store the last word in a variable. I'm just not sure how to get the last word.

Code:

#include <stdio.h>
#include <string.h>

int main() {
    FILE *f = fopen("data.txt", "r");
    char line[1000];

    while (fgets(line, sizeof line, f) != NULL) {
        char *last_tok = NULL;
        char *tok = strtok(line, " \t\n");
        while (tok) {
            last_tok = tok;
            tok = strtok(NULL, " \t\n");
        }
        if (last_tok)
            printf("%s\n", last_tok);
    }

    fclose(f);

    return 0;
}
