What is a constructor?

A constructor is a class member executed when an instance of the class is created. The constructor has the same name as the class, and it can be overloaded via different signatures. Constructors are used for initialization chores.

public class Taxi
{
    public bool isInitialized;
    public Taxi()
    {
        isInitialized = true;
    }
}

class TestTaxi
{
    static void Main()
    {
        Taxi t = new Taxi();
        Console.WriteLine(t.isInitialized);
    }
}
