C++ Ausgabefehler (Neuheiten hinzugefügt)

Question

Mein Programm scheint durch zwei Kurse nur ausgeführt werden, dann hört es auf und zeigt den zweiten Kurs 3 mal.

Ich bin ratlos und zog mir die Haare aus, würden irgendwelche Vorschläge viel helfen.

Ich entschuldige mich auch im Voraus für den langen Post, aber ich fühle mich alle Teile nötig sind, um das Problem zu identifizieren.

Hier ist die aktuelle Ausgabe: Current output

Meine erwartete Ausgabe ist:

Titel: Titel Kursnummer: 12345 Session: 54321 Einheiten: 1.2

Hier, wo der Fehler ist:

Hier ist die Überschrift:

    void Courses::setNumOfUnits(double units)

Answer 1

Ihr Konstruktor als Courses(string title, int course, int session, double units) deklariert wird

aber Sie nennen es als Courses Class_1(title, session, units, course);

nur wechseln um die Variablen und es sollte in Ordnung sein

Courses Class_1(title,course,session,units);
