Interface implementations and multiple inheritance in C++

Multiple inheritance of interfaces which are pure abstract classes indeed is not a problem until you need to use the interface implementation in other classes.

Suppose there are two interfaces, the implementation of which will be used in other classes.

Delphi and Free Pascal bencmark: array vs TList vs dynamic array

Let's perform a simple benchmark testing the random and sequential access to arrays and lists. I would like to compare:

  • static array with predefined size (allocated on stack)
  • TList container class (allocated on heap)
  • dynamic array (allocated on heap)
  • generic Delphi TList or Free Pascal TFPGList (allocated on heap)

I use an array/list of 10M elements of integer and varaint data type. You can change the type definition in "type" section if need to test other cases.

Crack C# namespaces in 30 seconds

The namespaces conception in C# seems to be exhaustive and insufficient at the same time compared with a strong module notation in Oberon-2 and even with a modular programming approaches in Free Pascal/Delphi.

Why insufficient? You cannot declare constants and functions within namespaces but you should add a class with constant field or static method for it.

Why exhaustive? The using directive with such introduced classes is the source of unexpected errors. Here is an example below.
