问题 In object-oriented(51), objects can be viewed as reusable components, and once the programmer has developed a(52)of these components, he can(53)the amount of new coding required. But(52)a(54)is no simple task because the integrity of the Original software design is critical. Reusability can be a mixed blessing for user, too, as a programmer has to be able to find the object he needs. But if(55)is your aim, reusability is worth the risk.

选项 A、complexity
B、creating
C、productivity
D、library
E、maximize

答案C

解析 在面向对象的程序设计中,对象可被看做是一种可重用的构件。一旦程序员开发了一个构件库,就可以使新程序需要的代码数量最小化。但是,建立一个构件库却并非易事,,因为最初的软件设计的完整性是很重要的。当程序员能找到所需要的对象时,对用户来说,可重用性是一个好坏参半的事情。但是,如果效率是你追求的目标,那么可重用性还是值得一用的。
