I want to ask you for your best practices regarding constructors in C++. I am not quite sure what I should do in a constructor and what not.
Should I only use it for attribute initializations, calling parent constructors etc.? Or might I even put more complex functions into them like reading and parsing configuration data, setting up external libraries a.s.o.
Or should I write special functions for this? Resp. init() / cleanup()?
What are the PRO's and CON's here?
I figured out yet that for example I can get rid of shared pointers when using init() and cleanup(). I can create the objects on the stack as class attributes and initialize it later while it is already constructed.
If I handle it in the constructor I need to instantiate it during runtime. Then I need a pointer.
I really don't know how to decide.
Maybe you can help me out?
