Which language are we talking here? Cpp? Because typeof hasn't ever seemed useful to me in how I use cpp or how I have ever really used a language. I also remember it being criticized in java class more than 20 years ago when OOP was solely preached, even for scientific people like me.
This sure looks like C#. I use typeof every once in a while when I want to check that the type of a reference is a specific type and not a parent or derived type. But yea, really not that often.
I have used typeof(T) inside the generic class, so fx a function inside the
class Piewhere T can be refered. But out of context, if you were to call typeof(T) inside Program.cs's main function, it would not work.
