I have been sitting on this simple fundamental mistake for a while.
How do we avoid strings in the stdin, that are bigger than a defined sizeof(sring). Here sizeof(stdin_passed) > sizeof(word_new). When we are restricted to use ferror or feof.

Thanks

int main() {
    int word_count= 0;
    char **word_ARRAY= malloc(sizeof(char*));
    if (word_ARRAY== NULL) {
        perror("malloc");
        exit(1);
    }

    char word_new[42];

    while(1) {
        /*help needed here: ouput is Segmentation Error*/

        if (fgets(word_new, sizeof(word_new), stdin) == NULL){
            // error occurs, thus use perror
            if(ferror(stdin)){
                perror("error occured in stdin");
                exit(1);
            }
            // no error and only EOF reached
            break;
        }
