Casting using typedef???

[Guest_imported]

I`m trying to cast a parent class to a child class using the typedef as a variable when casting but it comes up with the error, that it "expects a type def (typedef) when found a Shape":

// circle is a class
typedef Circle def;

// shape is a parent class for a child circle class
vector<Shape> Vec;

Shape shape1();

vec.push_back(shape1);
((def)shape1).data = &quot;hello&quot;;

Hi!
dynamic_cast Used for conversion of polymorphic types

For instance:
class A {
}

class Bublic class A{
}

...
A a;
B b
a = dynamic_cast<A>(b);
