public class ClassA
{
    public ClassA()
    {
        Console.WriteLine("Class A");
    }
}
public class ClassB : ClassA
{
    public ClassB()
    {
        Console.WriteLine("Class B");
    }
}
public class ClassC : ClassB
{
    public ClassC()
    {
        Console.WriteLine("Class C");
    }
}

What output will print after calling this statement
ClassC objC = new ClassC();

Constructors that are declared within a base class are not inherited by subclasses. As with any other class, a subclass with no constructors defined is provided with a default constructor that provides no explicit functionality. The constructors from the base class are not made available when creating new subclass object instances.
When a subclass is instantiated, the standard behaviour is for the default constructor of the base class to be called automatically. In this way, the base constructor can initialise the base class before the subclass' constructor is executed.
