Does it make sense to define new keywords in c++?

Question

C++ / C#

Below is a piece of code that shows why such an idea appeared.
I would like to know if this will only make it worse or will it increase the readability of the code and make it more pleasant to read?

#define dynamic auto
#define interface class
#define abstract = 0


interface ISomable
{
  /* Comment for this method. */
  void virtual CustomMethod() abstract;
};

dynamic vector = new int(2);

Answer 1

It will most likely be confusing.
Your interface is never an interface - by defining you can't forbid adding an implementation to it.
In general, such defines are dangerous - what if my variable name is abstract?
Well, auto on dynamic is generally pointless - tracing paper from another PL? What for? More letters, auto-substitution and IDE goodies may not adequately digest this.

Answer 2

1. #define in pros is evil
2. for plus signs your code will be unreadable
3. it is better to get used to the standard notation of pluses

Answer 3

Well, no, by no means. Considering what C++ is capable of, you will complicate your life and understanding of its syntax. It will be more difficult for you to understand someone else's code.
