这就是 Pascal 语言的设计者 Niklaus Wirth 将其著作命名为《算法 + 数据结构 = 程序》(Algorithms + Data Structures = Programs, Prentice Hall, 1975 )的原因。需要注意的是,在 Wirth 命名的书名中, 算法是第一位的,数据结构是第二位的,这就明确地表述了程序员的 工作方式。先要确定
To gain this scalable performance, programmers must rewrite existing programs to use new libraries [5]. Manual rewriting is labor intensive because many program fragments must be modi- fied consistently across all of the source files. This work is error- prone, because the programmer cannot easily...

1.1.2 Programs before the web Before the World Wide Web, programs were generated differently according to system on which they were intended to run: a program running on a Macintosh computer could not be used with another computer with a different operating system – the program that controls ...

Deprecated APIs are interfaces that are supportedonlyfor backwards compatibility. Thejavaccompiler generates a warning message whenever one of these is used, unless the-nowarncommand-line option is used. It is recommended that programs be modified to eliminate the use ofdeprecated APIs, though there...
