《编程入门：C、C++、Scheme、Prolog、C#与SOA第五版》由陈垠龙编著，专为初学者和专业人士设计，涵盖了五个主要编程语言——C、C++、Scheme、Prolog和C#，以及面向服务架构(SOA)的基础知识。本书适合那些希望系统学习不同编程语言及其特性的读者，无论他们是初次接触编程，还是寻求技术进阶。 第五版在2016年12月20日出版，共464页，全面介绍了编程语言的基本原则，包括编程概念和范式、编程语言的性能和特性，以及编程语言的发展历程。作者陈垠龙是亚利桑那州立大学的教师，结合丰富的教学经验和实践案例，帮助读者理解这些语言的内在逻辑和实际应用。 章节一“基本编程语言原理”作为全书的导引，首先从介绍编程的基本概念出发，区分编程的不同理念和方法论，比如过程式、面向对象、函数式等编程范式。接下来，讨论了编程语言的性能考量，包括执行效率、内存管理等关键因素，使读者对选择哪种语言有更深入的认识。 章节1.2进一步探讨了编程语言的结构，包括词法结构，即编程语言的符号和规则，这对于编写源代码和理解语言解析至关重要。这部分内容有助于读者掌握语法基础，以便在实际编码时避免常见错误。 此外，书中还特别关注了C#语言，作为一种现代面向对象编程语言，它在企业级应用和云计算领域有广泛应用。SOA（面向服务架构）的引入则扩展了读者对分布式系统和网络编程的理解，使读者能够理解和构建可扩展的、松耦合的软件系统。 版权方面，该书受到严格保护，未经许可，任何复制、存储或传播行为均需事先获得版权所有者书面许可。本书由Kendall Hunt Publishing Company出版，读者可以在其官方网站www.kendallhunt.com获取更多信息或联系出版商。 通过阅读本书，读者将建立起坚实的编程基础，了解并掌握多种编程语言的核心要素，为未来的编程生涯打下坚实的基础。无论你是新手还是寻求技术提升的专业人士，这本书都是一份宝贵的资源。

Write a code to calculate the trajectory that is traced out between time t=0 and t=20 by an air parcel in the flow: F(x, y)=-(y^2)/2+cos(x). Use the explicit (Euler forward) scheme for the first step, and the leapfrog scheme for all subsequent steps. Use △t = 0.01 and include a Robert-Asselin filter applied to both x and y with a coefficient of 0.01. You will need to import math to use the Python function math.sin(). Run your program for the following two starting positions, which are marked with crosses in the above figure:(x0.y0)=(1.0,1.0)
(in the eddy region)
,(x0,y0)=(1.0,2.0)
(in the stream region)
For each of these starting positions， plot the trajectory in the （x ，y） plane. Use the trajectory in the eddy region to verify the stability of the numerical method and explain your reasoning

Sure, here's a Python code that ... This is because the eddy region is known to have chaotic behavior, and if the method is stable in this region, it is likely to be stable in other regions as well.

Each letter in the alphabet can be given a value based on its position in the alphabet, A being 1 throughto Z being 26. Two letters can produce a third letter by adding together their values, deducting 26 fromthe sum if it is greater than 26, and finding the letter whose value equals this result.A simple encryption scheme for a string is as follows. Working from left to right, after leaving the left-most character alone, each character is replaced with the character produced by adding it to thecharacter to its immediate left.For example:• The string ENCRYPT goes through the steps ENCRYPT → ESCRYPT → ESVRYPT → ESVNYPT →ESVNMPT -> ESVNMCT -> ESVNMCW1(a) [ 24 marks ]Write a program that reads in an encrypted string, between 1 and 10 uppercaseletters inclusive, and outputs the original version of that string

2023-05-26 上传
Here's a Python program that implements the encryption scheme and decrypts the input string: ```python def decrypt(s): # convert string to list of ASCII codes code = [ord(c) - 64 for c in s] # ...

10.7 Consider a system that supports 5,000 users. Suppose that you want to allow 4,990 of these users to be able to access one fifile. a. How would you specify this protection scheme in UNIX? b. Can you suggest another protection scheme that can be used more effectively for this purpose than the scheme provided by UNIX?

2023-06-03 上传
To specify this protection scheme in UNIX, you can set the file permissions using the chmod command. Specifically, you can set the permission bits such that the owner and group have full access to ...

Could not find a file system implementation for scheme 'hdfs'. The scheme is not directly supported by Flink and no Hadoop file system to support this scheme could be loaded

This error message ...By configuring Flink with the appropriate Hadoop libraries and settings, it should be able to load the Hadoop file system implementation for the 'hdfs' scheme and work with HDFS.
