Most of problems are solved by decomposing to smaller ones, describing
the problem in more and more detail, or in different view.

A problem begins with the description of the problem.
Description of the natural language is basically the pattern Noun+Verb [+Noun],
which corresponds to object's function member call.
So, OOP is simulating natural sentences, making it 'objectively' executable by
machine. An unambiguous, efficient and machine-executable description is 
derived by repeated improvement of try-error.
So, OOP is 'just' a way to make our notion itself of the problem clear.

No matter how the programming problem is given, we do not start out having
a clear description of the problem. OOP is a method helps us understanding the
problem. Not strictly can a top-down process yield the program.

I just took a look of https://en.cppreference.com/w/cpp/filesystem (I am not
familiar with 'standard' things). It looks to me that the class (objects) are
actually 'string' (of special format), they are actually dealing with string
problems. The idea of that library is not much different from common 
C-programming. All the complexity pose more problems and solves little, very 
inefficient.
