Probably you are looking for get_current_user_id() function, not get_queried_object() function. get_queried_object() retrieve the currently-queried object. Instead you should use get_current_user_id( )
$user_id = get_current_user_id();
if ($user_id == 0) {
echo 'You are currently not logged in.';
} else {
echo 'You are logged in as user '.$user_id;
}
In order to info about the logged in user try
global $current_user;
get_currentuserinfo();
echo 'Username: ' . $current_user->user_login . "\n";
echo 'User email: ' . $current_user->user_email . "\n";
echo 'User first name: ' . $current_user->user_firstname . "\n";
echo 'User last name: ' . $current_user->user_lastname . "\n";
echo 'User display name: ' . $current_user->display_name . "\n";
echo 'User ID: ' . $current_user->ID . "\n";
