int main() {
    string line;
    int count = 0;
    char ch;
    cout << "Enter a line of string: "; // remove this line if prompt for input is not required
    getline(cin, line);
    for (int i = 0; i < line.size(); ++i) {
        ch = line[i];
        if (ch != ' ' && ch != '.' && ch != ',')
            ++count;
    }
    cout << count << endl;
