Question

My task is to write a program which is supposed to omit a single word after a specific sequence in the previous ones.
I’ve already prepared a working getword procedure (returns char *), now I only have problems with main where I have the following snippet of code, which allows me to detect where should I remove the word. But I don’t know how to actually omit/remove that word from the outfile.

int main(int argc, char **argv)
{
    FILE *infile = NULL, *outfile = NULL;
    char *word = NULL;
    int c;
    int yes = 0;
    int counter = 0;

    /* completely irrelevant - opening, writing to files, error messages etc. */
    while (1) {
        c = fgetc(infile);

        word = getword(infile);
        if (counter == 2) {
            counter = 0;
            yes = 0;
                    /* here it should somehow omit the word */
            continue;
        }
        if (choose(word, strlen(word))) {
            fputs(word, outfile);
            counter++;
            yes = 1;
        } else {
            fputs(word, outfile);
            if (yes == 1) {
                counter--;
            }   
        }
        free(word); 
    }
    /* completely irrelevant */
}   

EDIT: Added to clarify

“getword just reads a word, it doesn’t perform any check whether it is the word I’m looking for. main() does that check. When the if (choose) is satisfied then it means that word contains sequence of letters I’m looking for, and the second word after that particular word should be omitted. Variables “counter” and “yes” may not be the perfect algorithm, but at first I want it to work, then I’ll try to simplify that. “Counter” counts up to 2 to determine which word is to be omitted, and “yes” helps to increment the counter after we move to a word not satisfying if (choose) condition.”

Thanks in advance!

Answer 1

I got it, in the place of

/* here it should somehow omit the word */

there should be free(word);

Everything works like charm.
I got it earlier, but forgot to post answer to my own question 😀
