[单选题]The beauty of software is in its function, in its internal structure, and in the way in which it is created by a team. To a user, a program with just the right features presented through an intuitive and( 71 )interface is beautiful. To a software designer, an internal structure that is partitioned in a simple and intuitive manner, and that minimizes internal coupling is beautiful. To developers and managers, a motivated team of developers making significant progress every week, and producing defect-free code, is beautiful. There is beauty on all these levels.

A beautiful software system can be built and maintained in less time, and for less money, than an ugly one. Novice software developers don't understand this. They think that they have to do everything fast and quick. They think that beauty is( 作答此空 ). No! By doing things fast and quick, they make messes that make the software stiff, and hard to understand, Beautiful systems are flexible and easy to understand. Building them and maintaining them is a joy. It is ugliness that is impractical. Ugliness will slow you down and make your software expensive and brittle. Beautiful systems cost the least build and maintain, and are delivered soonest.
