Most programmers know that having functions with too many parameters can be confusing. However, fixing such problems requires some intelligence. A programmer once saw some code like this:
SetObjectParams(obj, foo, bar, baz, quux, xyzzy, abra, cadabra, hocus, pocus, presto, shazam);
Finding a stylistic rule somewhere that said a function should have no more than five parameters, the programmer “refactored” it to this:
SetObjectParams1(obj, foo, bar, baz, quux); SetObjectParams2(obj, xyzzy, abra, cadabra, hocus); SetObjectParams3(obj, pocus, presto, shazam);
No, that's not how one resolves this problem. You fix this problem by defining functions that each do something simple, give each function a name that describes what it does, and let them take however many parameters make sense.
