单项选择题Why is ______ fun What delights may its practitioner

expect as 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. Second is the pleasure of making things that are useful to

other people. Third is the fascination of fashioning complex puzzle-like objects

of interlocking moving parts and watching them work in subtle cycles, playing

out the consequences of principles built in from the beginning. Fourth is the

joy of always learning, which springs from the ______ nature of the task. In one

way or another the problem is ever new, and its solver learns

something：sometimes ______, sometimes theoretical, and sometimes both. Finally,

there is the delight of working in such attractable medium. The ______, like the

poet, works only slightly removed from pure thought-stuff. Few media of creation

are so flexible, so easy to polish and rework, so readily capable of realizing

grand conceptual structures.

Yet the program ______, unlike the

poet’s words, is real in the sense that it moves and works, producing visible

outputs separate from the construct itself. It prints results, draws pictures,

produces sounds, moves arms. Programming then is fun because it gratifies

creative longings built deep within us and delights sensibilities we have in

common with all men.将C语言编写的源程序转换为目标程序的软件属于______。
