Daily DRY Tip

DRY stands for Don’t Repeat Yourself. A paradigm that is indispensible in software engineering.
Since I enjoy writing concisely more than going extra-elaborate, I will keep this post as concise as possible.

Example of code that is has not DRY’ed out completely :

class Classy
{
  public:
    static Classy Schmassy() ;

};

int main()
{
  Classy  obj = Classy::Schmassy() ;

  return 0 ;
}

What could be the darned problem with such a tiny crumble of code? The un-DRY’ness of this code can be found in the body of the main() function.

If we let some sun shine on it, it DRY’s out completely.

int main()
{
  Classy  obj = obj.Schmassy() ;

  return 0 ;
}

There you go, just one reference to the concrete type.
