void find_second_largest_word_in_string(char string[], char second_largest[]) {
    char largest[16] = "";
    int found_second = 0;

    char* word = strtok(string, " ,.-");

    while (word != NULL) {
        if (strlen(word) > strlen(largest)) {
            strcpy(second_largest, largest);
            strcpy(largest, word);
        }
        else if (strlen(word) > strlen(second_largest) && !found_second) {
            strcpy(second_largest, word);
            found_second = 1;
        }

        word = strtok(NULL, " ,.-");
    }
}

int main(void)

    char string[] = "c cpp cobol c# python java";
