A Comparison of C++, C#, Java, and PHP in the Context of E-Learning A Comparison of C++, C#, Java, and PHP in the context of e-learning MIKAEL OLSSON KTH Information and Communication Technology Master of Science Thesis Stockholm, Sweden 2009 TRITA-ICT-EX-2009:8 A Comparison of C++, C#, Java, and PHP in the context of e‐learning Mikael Olsson April 30, 2009 Master’s Thesis in Computer Science Royal Institute of Technology Examiner: Prof. Gerald Q. Maguire Jr. ‐ i ‐ Abstract The first part of this master thesis presents an effective method for producing video tutorials. This method was used during this thesis project to create tutorials on the e- learning site PVT (http://www.programmingvideotutorials.com). Part one also discloses how the production method was developed and how tutorials produced using this method compare to professional video tutorials. Finally, it evaluates the result of this thesis work and the efficiency of the production method. The second part of this thesis compares the syntactical similarities and differences between four of the languages taught via video tutorials for PVT. These languages are: C++, C#, Java, and PHP. The purpose of this comparison is to provide a bridge for programmers knowing one of these languages to rapidly learn one or more of the other languages. The reason why this would be necessary is because there is no single language suited for every area of software development. Knowing a multitude of languages gives a programmer a wider range of job opportunities and more choices in how to solve their problems. Part two of the thesis also includes a comparison of Java and C# in the context of a video tutorial series that shows how to build a basic text editor. Sammanfattning Den första delen av denna examensredovisning beskriver en effektiv metod för att producera videokurser. Denna metod har använts under detta examensarbete för att skapa kurser på utbildningssajten PVT (http://www.programmingvideotutorials.com). Del ett berättar också hur produktionsmetoden utvecklades och hur kurser producerade enligt denna metod står sig mot professionellt skapade videokurser. Slutligen utvärderas resultatet av examensarbetet och effektiviteten av produktionsmetoden. Den andra delen av denna redovisning framför de syntaktiska likheterna och olikheterna mellan fyra av de språk som har lärts ut via videokurser på PVT. Dessa språk är: C++, C#, Java, och PHP. Meningen med denna jämförelse är att underlätta för programmerare som kan ett av dessa språk och som snabbt vill lära sig ett eller flera av de andra språken. Anledningen till varför detta skulle vara nödvändigt är för att det inte finns något enstaka språk anpassat till alla områden av programutveckling. Att kunna ett flertal språk ger en programmerare ett bredare utbud av jobbmöjligheter och mer val i hur han eller hon kan lösa sina problem. Del två av redovisningen inkluderar också en jämförelse av Java och C# i sammanhanget av en videokurs som visar hur man bygger en enkel text editor. ‐ ii ‐ Table of Contents 1.

  • C and C++ Preprocessor Directives #Include #Define Macros Inline
    MODULE 10 PREPROCESSOR DIRECTIVES My Training Period: hours Abilities ▪ Able to understand and use #include. ▪ Able to understand and use #define. ▪ Able to understand and use macros and inline functions. ▪ Able to understand and use the conditional compilation – #if, #endif, #ifdef, #else, #ifndef and #undef. ▪ Able to understand and use #error, #pragma, # and ## operators and #line. ▪ Able to display error messages during conditional compilation. ▪ Able to understand and use assertions. 10.1 Introduction - For C/C++ preprocessor, preprocessing occurs before a program is compiled. A complete process involved during the preprocessing, compiling and linking can be read in Module W. - Some possible actions are: ▪ Inclusion of other files in the file being compiled. ▪ Definition of symbolic constants and macros. ▪ Conditional compilation of program code or code segment. ▪ Conditional execution of preprocessor directives. - All preprocessor directives begin with #, and only white space characters may appear before a preprocessor directive on a line. 10.2 The #include Preprocessor Directive - The #include directive causes copy of a specified file to be included in place of the directive. The two forms of the #include directive are: //searches for header files and replaces this directive //with the entire contents of the header file here #include <header_file> - Or #include "header_file" e.g. #include <stdio.h> #include "myheader.h" - If the file name is enclosed in double quotes, the preprocessor searches in the same directory (local) as the source file being compiled for the file to be included, if not found then looks in the subdirectory associated with standard header files as specified using angle bracket. - This method is normally used to include user or programmer-defined header files.

  • Guide to C Files and H Files by Jacob “Bob” Egner Introduction This
    Guide To C Files And H Files by Jacob “Bob” Egner Introduction This document explains the philosophy of C and H files, and what to put in each file type. At times, I'll stray from the main topic to talk about C compilation in general. The more you understand about C compilation, the less trouble you'll have getting your programs to compile and work. Along with this document, you should also have the files heap.h, heap.c, and heap_test.c. This project can be found in the starter files section of the web site. heap.c and heap.h make up a “module” that implements a memory heap. heap_test.c uses the heap module. I wrote these files to be examples for this document, bring dynamic memory management to the 9S12, and mostly for fun. Please glance over these files before proceeding. The project can be found in the “Starter files” section of the course web site. Why Do We Have H Files? One key thing in understanding C and H files is that declaration and definition are two different things. A declaration tells the compiler that something exists and what kind of beast it is. A definition tells the compiler what it is. A function declaration tells the name of a function, what arguments it takes and what it returns. A function definition also has all that and the code that implements the function. A variable declaration tells the type of a variable. A variable definition tells the type and actually allocates space for the variable.

In this paper, we will discuss ten programming languages: C++, C#, Java, Groovy, JavaScript, PHP, Schalar, Scheme, Haskell and AspectJ. We summarize and compare these ten languages on ten different criterion. For example, Default more secure programming practices, Web applications development, OO-based abstraction and etc. At the end, we will give our conclusion that which languages are suitable and which are not for using in some cases. We will also provide evidence and our analysis on why some language are better than other or have advantages over the other on some criterion. 1 Introduction Since there are hundreds of programming languages existing nowadays, it is impossible and inefficient

  • Programming with Windows Forms
    A P P E N D I X A ■ ■ ■ Programming with Windows Forms Since the release of the .NET platform (circa 2001), the base class libraries have included a particular API named Windows Forms, represented primarily by the System.Windows.Forms.dll assembly. The Windows Forms toolkit provides the types necessary to build desktop graphical user interfaces (GUIs), create custom controls, manage resources (e.g., string tables and icons), and perform other desktop- centric programming tasks. In addition, a separate API named GDI+ (represented by the System.Drawing.dll assembly) provides additional types that allow programmers to generate 2D graphics, interact with networked printers, and manipulate image data. The Windows Forms (and GDI+) APIs remain alive and well within the .NET 4.0 platform, and they will exist within the base class library for quite some time (arguably forever). However, Microsoft has shipped a brand new GUI toolkit called Windows Presentation Foundation (WPF) since the release of .NET 3.0. As you saw in Chapters 27-31, WPF provides a massive amount of horsepower that you can use to build bleeding-edge user interfaces, and it has become the preferred desktop API for today’s .NET graphical user interfaces. The point of this appendix, however, is to provide a tour of the traditional Windows Forms API. One reason it is helpful to understand the original programming model: you can find many existing Windows Forms applications out there that will need to be maintained for some time to come. Also, many desktop GUIs simply might not require the horsepower offered by WPF.
