　　For courses in C++ Programming 　　Fundamentals of C++ for Novices and Experienced Programmers Alike 　　Intended for use in a two-term, three-term, or accelerated one-term C++ programming sequence, this Ninth Edition of Starting Out with C++: Early Objects introduces the fundamentals of C+

+ to novices and experienced students alike. In clear, easy-to-understand terms, the text introduces all of the necessary topics for beginning C++ programmers. Real-world examples allow students to apply their knowledge in understanding how, why, and when to implement the features of C++. The text i

s organized in a progressive, step-by-step fashion that allows for flexibility. Building on the popularity of previous editions, the Ninth Edition has been updated and enhanced with new material, including C++11 topics and recent changes in technology. 　　MyProgrammingLab?not included. Students, if

THE PRACTICE OF COMPUTING USING PYTHON 3/E (GE)

為了解決Android read file li的問題，作者PUNCH,ENBODY 這樣論述：

　　For courses in Python Programming 　　Introduces Python programming with an emphasis on problem-solving 　　Now in its Third Edition, Practice of Computing Using Python continues to introduce both majors and non-majors taking CS1 courses to computational thinking using Python, with a stron

g emphasis on problem solving through computer science. The authors have chosen Python for its simplicity, powerful built-in data structures, advanced control constructs, and practicality. The text is built from the ground up for Python programming, rather than having been translated from Java or C+

+. 　　Focusing on data manipulation and analysis as a theme, the text allows students to work on real problems using Internet-sourced or self-generated data sets that represent their own work and interests. The authors also emphasize program development and provide both majors and non-majors with a

practical foundation in programming that will be useful in their respective fields. Among other changes, the Third Edition incorporates a switch to the Anaconda distribution, the SPYDER IDE, and a focus on debugging and GUIs. 　　MyProgrammingLabot included. Students, if MyProgrammingLab is a recomm

ended/mandatory component of the course, please ask your instructor for the correct ISBN and course ID. MyProgrammingLab should only be purchased when required by an instructor. Instructors, contact your Pearson representative for more information. 　　MyProgrammingLab is an online learning system de

signed to engage students and improve results. MyProgrammingLab consists of a set of programming exercises correlated to specific Pearson CS1/Intro to Programming textbooks. Through practice exercises and immediate, personalized feedback, MyProgrammingLab improves the programming competence of begin

ning students who often struggle with the basic concepts of programming languages. 本書特色 　　About the Book 　　●NEW! A switch to Anaconda distribution, made freely available from Continuum Analytics, includes more than 100 pre-installed modules, removing the need for package installation. 　　●NEW! Fu

lly adopted SPYDER Integrated Development Environment as a default method for editing and debugging code in the text. A truly modern IDE, Spyder has the advantages of including an integrated editor, associated interactive console, integrated debugging, integrated variable explorer, and integrated do

cumentation viewer. Chapter 1 has been rewritten to incorporate the SPYDER IDE. 　　●NEW! Anaconda also includes the iPython console, a more capable console, with features including: 　　○An interactive history list 　　○Help on functions and variables using the “?” syntax 　　○Command line completion 　　●

UPDATED! iPython console incorporated in every session with its features sprinkled throughout the text. 　　●NEW! “What’s wrong with my code” element has been added to several chapters to address the challenge of debugging. 　　●UPDATED! “Visual Vignettes” have been updated and simplified. 　　●NEW! Si

mple GUI development is included in several chapters, as well as a new appendix on web-based GUIs in response to student interest. 　　●NEW! 80 new end-of-chapter exercises are included. 　　●UPDATED! Chapter 16 provides discussion about Python Numbers and the various representations that are availabl

e. 　　●REVISED! Chapter 5 has been rewritten to not depend on Chapter 4, allowing instructors to choose the order in which they introduce concepts of strings and functions. 　　●Problem solving and case studies are emphasized throughout the text, including in 3 optional chapters (3, 10, and 13) that

use examples to show mistakes and how to recover from them. 　　●Real-world, gender-neutral examples and exercisesencourage students to use Python to sort, apply, graph, and convert data. Examples include poker hands, the Gettysburg Address, EPA mileage data, breast cancer classifier, speech analysis

, political debates, and S&P 500 analysis. 　　●An “object-use-first” approach is taken, with the authors using objects and methods early, while leaving the design and implementation of objects for later in the text, once mastery of the use of objects has been achieved. 　　●A traditional CS1 orde

r with some significant differences, including: 　　○Strings are covered early (before functions) to allow for more data manipulation early in the text. 　　○File I/O is covered early for the same reason as strings. 　　○Topics such as plotting and drawing are included throughout the text in service of th

e data manipulation theme. 　　●Incorporates data structures as early as possible, including lists and strings, which show up before they are covered in detail. 　 　　●Drawing and graphing packages are incorporated and covered in the appendices. 　　●Over 180 code examples illustrate piecemeal developme

nt of larger problems. 　　●Almost 250 interactive sessions are provided to illustrate programming and problem-solving concepts. 　　●Over 275 short exercises and nearly 30 longer programming projects, many with multiple parts, are included. 　　●24 self-check exercises are embedded within the chapters

, each with 5 or more associated questions. 　　●Over 40 notes provide useful programming tips and are boxed for emphasis.  　　MyProgrammingLab™not included. Students, if MyProgrammingLab is a recommended/mandatory component of the course, please ask your instructor for the correct ISBN and course ID

. MyProgrammingLab should only be purchased when required by an instructor. Instructors, contact your Pearson representative for more information. 　　MyProgrammingLab is an online learning system designed to engage students and improve results.

ises correlated to specific Pearson CS1/Intro to Programming textbooks.

雙訊息QR Code之研究

為了解決Android read file li的問題，作者周國健 這樣論述：

QR code是當今全球最流行的二維條碼之一，已成功並廣泛應用於製造、運輸、醫療保健、辦公自動化、零售和廣告等多個領域的物品識別、定位和追踪。QR code有幾個吸引人的特性，包括大容量資料存儲、資料損壞高容忍度及任何方向的可讀性和快速解碼。此類代碼提供了一種無需繁瑣打字即可快速存取資料的方法，其非接觸式的資料擷取模式在當前 COVID-19 時代，用於開發交互式應用程式具有巨大潛力。通常一個標準QR code僅可以儲存單一訊息，然而，一個QR code若能儲存多個訊息，在許多情況下會非常實用，因此，在近年來，多層訊息QR code之研究已蔚為流行，亦為本論文的主要研究方向。本論文提出三種單

一QR code可以包含雙訊息的新方法，第一種方法稱為嵌入式QR code，第二種方法稱為雙重訊息QR code，兩種方法皆是藉由調整掃描距離來分別讀取訊息的方式，一個訊息從近距離掃描讀取，而另一個訊息是從遠距離掃描讀取，與文獻中的兩層QR code方法相比，我們的方法具有以下優點：（1）兩個訊息均可由一般的QR code掃描應用程式讀取，無需專用的QR code掃描應用程式或額外計算，（2）QR code可以由軟體程式產生後直接列印使用，無需耗時與高成本的實體製造過程。除此之外，所提出的方法可以在單一QR code鏈結兩項資訊，例如某公司的一個網頁和一段影音介紹，或一個產品的兩種語言說明等，

實驗結果亦驗證了所提方法的可行性。第三種新方法，稱之為模組導引半色調QR code，它不僅可對規範之文字串進行編碼，而且還可向觀看者展示額外的視覺訊息，它繼承了標準QR code的黑白特性，可以經濟地列印出來。在文獻中，半色調QR code通常是通過進行大量可讀性實驗來設計的，並且通常將模組中央三分之一區域設置為原始模組顏色，以確保解碼訊息正確，在本論文中，推導出了用於正確解碼QR code所需模組中心區域大小的理論值，並因此提出了一種快速有效產生半色調QR code的方法。實驗結果驗證了所提方法的有效性，並顯示其所產生的半色調QR code具有適當的解碼穩健性和良好的視覺品質。我們相信本論文

中提出之雙訊息QR code方法，對於QR code的發展開啟了全新的視野；研究結果還發現，美學QR code模組中央三分之一區域必須設置為原QR code模組顏色之限制已非必要，因此，在不影響其可讀性的情況下，有效提高了美學QR code的品質，亦可將其應用於資料安全管控；另雙訊息QR code亦可結合自然圖像，以及開發多層資訊QR code，和更多的互動創意應用。
