Good morning, Say I have a class ClassA , an operator + which sums

  • 0

Good morning,

Say I have a class ClassA, an operator + which sums up two objects of type ClassA, an implicit casting from intto ClassA, and that I want to overload the operator ++… Supposing the code for + is rather long, but that the sum of a ClassA and 1 is a very particular case of it, which option is better?

  1. Implement ++ using + and the implicit casting already defined.
  2. Repeat part of the code which simplifies alot when adding just 1.

My idea is that (2) is better since it saves the creation of a new ClassA object by the implicit casting, which can be quite useful if the ++ operator is used, for example, in a for cycle. Also, speed is a must.

Thank you very much.

    Either way is acceptable. It sounds like the second way is what you’re already leaning towards, so try it. In fact, try it both ways and measure the time it takes to increment a million times. Benchmarking is always the way to make these decisions.

    In case you haven’t done any benchmarking before, the simplest way is to create a System.Diagnostics.Stopwatch and start/stop it around the relevant code. You can then write the elapsed time to a console.
