Many scientists are devoting themselves to settle this problem . now , different scale reusable components had been built by many programming languages . these reusable components have improved the efficiency of program development greatly 目前許多程序設(shè)計環(huán)境都建有不同規(guī)模的可重用程序部件庫,這些可重用部件極大地提高了程序開發(fā)的效率。
Many evidences indicate reuse - driven software is a good way to solve software crisis . people can construct a lot of applications by the components , so much overlap work can be reduced and automation of arithmetic - building can be realized ultimately in this way 大量實踐表明,軟件復(fù)用是一種解決“軟件危機”的有效手段,用戶利用可重用程序部件庫中的部件可以組裝成各種應(yīng)用程序,這樣可以減少大量的重復(fù)性勞動,最終實現(xiàn)算法生成的自動化。
