    Compiler provides its default constructor to build the object. Default constructor has no argument or it is parameter less constructor. If there is no constructor available in a class, the compiler implicitly creates a default parameterless constructor .If a derived class constructor does not explicitly call the base class constructor then, the default constructor for the base class is called.
    Example:
    class myClass
    {
    myClass() { } // default constructor.
    };
