I'm looking for the C/C++ comparable way of doing <input type="password" /> for allowing the user to type in their password after a prompt in a command-line tool written in C.

string username;
string password;
cout << "Username: ";
getline(cin, username);
cout << "Password: ";
    [<input type="password" />]
getline(cin, password);
