question about classes and subclasses

[John S]

What is the difference execution wise between the following:

First example

Code Select Expand


class SomeBaseClass
{
  // a lot of something here
}

class SomeChildClass : SomeBaseClass
{
  // some more stuff here
}



Second example

Code Select Expand


class SomeBaseClass
{
  // a lot of something here
}

class SomeOtherClass
{
  SomeBaseClass BaseClassObject;

  // some more stuff here
}


In both examples there is inheritance, etc.  Which codes more efficiently?  This is relevant to the Vector/Array stuff I've been working on.

Both examples are not inheritance.  Only the first one is.

In the second example you have a member variable of some other class, which is slightly longer codewise when you execute a method in the member variable.

Thanks for the quick response, Paul.
