};

Ich habe das string ja includiert .

Warum wird trotzdem ein fehler angezeigt?

};

welchen operator willst du überladen? Das rop . Daher habe ich das grösser Zeichen umgedreht verwirrt

Ich habe mal versucht den Konstruktor zu implementieren ,habe allerdings probleme .

Wie soll ich denn den Konstruktor genau implementieren ?

using namespace std;

CTeam::CTeam( string name = "NoName"){

	m_name = name;
}

Es steht nicht genaues dabei verwirrt

Existiert die Variable m_name? Bei deinem letzten Beitrag hieß sie m_teamName.

Es wird ein error für teamName angezeigt ?

Hier wird mir im Header fehler angezeigt ? Warum

Im Header darfst du keine Defalut Werte eintragen, wenn ich es richtig in Erinnerung habe. Nur in der cpp Datei.
Die Variable teamName in Zeile 14 wurde nicht definiert.

Soll ich einfach int teamName;

Im cpp erstellen ?

}
Fällt dir da was auf?
Entscheide dich für einen Namen, dann ist alles in Ordnung.

}

Die übergebenen Parameterwerte werden außerdem im jeweiligen Attribut für die Gesamtzahl der eigenen Tore bzw. der Gegentore aufsummiert.

Was mit dieser Aufgabe genau gemeint ist verstehe ich nicht großes Grinsen

Was muss ich da genau machen ?

Weiss jemand aber wie ich die Ausgabe mithilfe des operators machen kann ?

Weil ich glaube mein Ansatz stimmt nicht so ganz großes Grinsen

Ein Team angelegt, es spielen lassen und dann ausgegeben.
Einfach nur um die Funktionalität zu testen.
