The purpose of the Constructors is to construct an object of that very type. Declaring it virtual is meaningless because by the time a constructor is called, compiler knows the exact type of the object to create.
It is the same reason that virtual functions called from within a constructor bypass the virtual call mechanism. Because within a CTOR, the exact object type is known, compiler can directly call the correct version without having to go thru the vfn table.

But in Java it is able to call overridden method from Ctor? So can constructor be virtual in those languages?
