class Three : One
{
Tw o p , q ;
public Three()
{
p= new Tw o ( new One(), 1);
p.GetO().SetX(7);
q= new Two(p.GetO(), 2);
q.GetO().SetX(8);
p= new Tw o ( this , 3);
p.GetO().SetX(9);
}
}
Make a drawing of what the memory looks like after executing:
Three t = new Three();
Just like the examples in this topic, make a clear distinction between the name
and the value of the variables: the name should be next to the boxes, and the
value in it. Object-references should start with a clear dot inside the box of the
reference variable, and point to the border of the object.
8. Classes and inheritance
Given are the following class definitions:
class A
{
public float var1;
protected int var2;
private bool var3;
public float Var1
{
get { return var1; }
}
public int Var2
{
get { return var2; }
set { if ( value > 0) var2 = value ;}
}
public void MethodInA()
{
...
}
}
