Delphi case

Delphi supports interfaces natively. Any variable of variant type can store an interface like any allowed data types.

Submitted by st on Mon, 24/07/2017 - 20:30

Pro et contra

I use C++Builder 10.1 (Berlin) that proposes both 'classic' bcc32 compiler and new clang bcc32c. Whether do you rather to use classic compiler or to switch to clang? The answer is not quite simple.

The advantages of new clang compiler:

Since early XE versions C++ Builder supports Delphi units directly added in C++ project and compiles them as well as C/C++ source. However, this approach has several drawbacks:

Happy tickets benchmark

Submitted by st on Sat, 13/02/2016 - 10:49

Some countries have integer numbers printed on the transport tickets, for example, in ex-USSR. The ticket is "happy" when the sum of the first half of digits equals to the second one. Then you should eat it and make a wish.

Example:

123456 and 111222 are not happy tickets
123123 and 123222 are the happy tickets

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.

Many years ago we had a need to manipulate the data of types "date" and "time" (DateTime in C# and Delphi/C++Builder). I had developed the corresponding class for these purposes.

Here is the interface with comments:
