Udfordring: Afledte Klasser
Stryg for at vise menuen
En klasse kaldet Vehicle er givet. Derudover er der to andre klasser kaldet Car og Plane.
Der er i øjeblikket en fejl i koden. For at rette fejlen skal du få Car og Plane til at arve fra Vehicle.
Rediger koden, så Car og Plane bliver underklasser af Vehicle.

Brug symbolet : i syntaksen for en afledt klasse for at angive forældreklassen.
