How do I get ispunct() function to work when reading from text file? c++

The rest of the code works fine but the ispunct() function is currently not reading any of the digits, such as a period or exclamation point, it's just counting total characters I am pretty sure. How do I get ispunct() to calculate the number of digits (.,!) from a text file?

void countChar();

int main() {
  ifstream myText("text.txt");
  char ch;

  if (!myText.is_open()) {
    cout << "The input file could not be opened." << endl;
    return 1;
  }

  else {
    countChar();
  }
}

void countChar() {
  ifstream myText("text.txt");
  char ch;
  int upper = 0, lower = 0, punct = 0;

  while (!myText.eof()) {
    myText.get(ch);

    if (islower(ch)) {
      lower++;
    } else if (isupper(ch)) {
      upper++;
    } else (ispunct(ch)); {
      punct++;
    }
  }
  myText.close();
  cout << "Uppercase characters: " << upper << endl;
  cout << "Lowercase characters: " << lower << endl;
  cout << "Digits: " << punct << endl;
}
