Why is(1)fun? What delights may its practitioner espect his reward? First is the
sheer joy of making things.As the child delights in his mud pie,so the adult enjoys
building things,especially things of his own design.Secong is the pleasure of making
things that are useful to other people.Third is the fascinanon of fashioning complex
puzzle-like objects  of interlocking moving  parts and watching them  work in subtle
eyeles,playing out the consequences of principies built in from the beginning.Fourth
is the joy of always learning,which springs from the(2)nature of the task.In one way
or    another    the    problem    is    ever    new,and    its    solver    learns
something:sometimes(3),sometimes  theoretical,and  sometimes both.Finally,there  is
the delight of working in such a tractable medium.The(4),like the poet,works only
slightly removed from nure thought-stuff.Few media of ereation are so flexible,so easy
to polish and rework,so readily capable of realizing grand conceptual structures.
Yet the program(5),unlike the poet’s words,is real in the sense that it moves and
works,producing  visible  outputs  separate  from  the  comstrct  itself.It  prints
results,draws pictures,produces sounds,moves arms.Progamming then is fun because it
gratifies creative longings built deep within us and delights sensibities we hav e in
common with all men.
