this is my current read file code:

```
void Dictionary::processFile() {
    ifstream fin;
    fin.open("article.txt");
    if (fin.fail( )) {
        cout << "Input file opening failed.\n";
        exit(1);
    }

    string word;

    while (!fin.eof()) {
        fin >> word;
        cout << word << endl;
    }
    cout << endl;
    fin.close();
}

```

How can I make my code ignore symbols(".';:! etc.) and only output/read words? at the moment it is reading every single symbol on the article. example "test.", "them,"
