Inheriting methods C# with Example

There are several ways methods can be inherited 
public abstract class Car 
{ 
public void HonkHorn() { 
// Implementation of horn being honked 
} 
 

// virtual methods CAN be overridden in derived classes 
public virtual void ChangeGear() { 
// Implementation of gears being changed 
} 
// abstract methods MUST be overridden in derived classes 
public abstract void Accelerate(); 
} 
public class Mustang : Car 
{ 
// Before any code is added to the Mustang class, it already contains 
// implementations of HonkHorn and ChangeGear. 
// In order to compile, it must be given an implementation of Accelerate, 
// this is done using the override keyword 
public override void Accelerate() { 
//  Implementation  of  Mustang  accelerating 
} 
// If the Mustang changes gears differently to the implementation in Car 
// this can be overridden using the same override keyword as above 
public override void ChangeGear() { 
// Implementation of Mustang changing gears 
} 
}
