1.5 An Analogy

Windows programming is complicated. Windows class libraries make Windows programming
simpler. True or false?

Sincerely, if you want to write programs that are precisely like the inventors of MFC or OWL
figured out you would, and you don’t care regarding the overhead, then by means of class
libraries and application wizards is the method to go. But any time you desire to step outside of
this path, you’ll find yourself in profound problem.
Let us provide you an analogy. Visualize that you’re purchasing a set of Lego blocks. You can
obtain a general purpose set, or you can purchase a particular set for structuring a pirate ship. If
you want to do to build a pirate ship, the second option is superior. But if you attempt to make
a Lego car, you’ll have to conquer a few troubles. Finally you’ll come up with something that
looks like a car, but it will have a humorous steering wheel, utilize an anchor for breaking, and
the driver will have a stick leg and a black patch over his eye.
After functioning with this Pirate Lego set for a while, you will turn out to be a specialist in
constructing approximately anything that could be built with a common purpose set. You’ll
learn all the tricks — like how to remove the patch from the pirate’s eye, how to paint over the
skull and crossbones, etc. Eventually you’ll arrive at a point when the amount of information
you’ve assimilated regarding the Pirate set will be much more than the fundamental engineering
principles you’d have to learn so as to use general purpose Lego. From that point on, you’ll be
throwing good money after bad money, investing in growingly complicated (and complicated)
Pirate sets.
