Design question
Author
I am making a sound synthesizer, so I want to create different types of waves for notes. Such as: sin wave, trianhle waves, etc.
In short, I did the following:
Is this a good way to solve this problem? or can the pointer cause some bugs?
Thanks in advance.
It's not a very good idea to have a BaseClass.
The name SynthesizerTypeCreator doesn't describe very well what it does. I would rather call it Synthesizer.
Your derived classes (SquareSynthesizer and SinSynthesizer) should have constructors that take whatever parameters they need (in those two cases, a frequency will do) and data members to store them.
I would also write a factory that would be able to construct any type of Synthesizer from a description (probably a text string). That way the rest of the code will not see the derived classes and you can add new Synthesizers without even recompiling the rest of the program.
Why is your rating 0? What did you do?

These are good ideas, but I think it is a bit overkill.
I just feared there might be a bug for using a pointer instead of a reference, but I dont think I can replace the pointer with a reference in this case.
Why I have a zero rating? perhaps an art statement?
