A derived class inherits the behaviours of a base class which means a child inherits the characteristics of a parent. it's possible, right? Think the other way round. Actually in the above code you are not trying call the constructor but you are trying to assign an instance of base class object to its' own child which is not possible.

ok thnx

Derived class can call base constructor only in their own constructor, see, for instance:

Just do this...

In your rectstyle class create a constructor like this

public rectstyle(double a, double b)
:base (a,b)
{

}

Then just create the object like this...

rectstyle = new rectstyle (double a,double b);
