Comparative Studies of Six Programming Languages
Comparative Studies of Six Programming Languages Zakaria Alomari Oualid El Halimi Kaushik Sivaprasad Chitrang Pandit Concordia University Concordia University Concordia University Concordia University Montreal, Canada Montreal, Canada Montreal, Canada Montreal, Canada [email protected] [email protected] [email protected] [email protected] Abstract Comparison of programming languages is a common topic of discussion among software engineers. Multiple programming languages are designed, specified, and implemented every year in order to keep up with the changing programming paradigms, hardware evolution, etc. In this paper we present a comparative study between six programming languages: C++, PHP, C#, Java, Python, VB ; These languages are compared under the characteristics of reusability, reliability, portability, availability of compilers and tools, readability, efficiency, familiarity and expressiveness. 1. Introduction: Programming languages are fascinating and interesting field of study. Computer scientists tend to create new programming language. Thousand different languages have been created in the last few years. Some languages enjoy wide popularity and others introduce new features. Each language has its advantages and drawbacks. The present work provides a comparison of various properties, paradigms, and features used by a couple of popular programming languages: C++, PHP, C#, Java, Python, VB. With these variety of languages and their widespread use, software designer and programmers should to be aware -

Creating a Portable Pascal Codebase
Creating a portable Pascal codebase. Marco van de Voort March 2, 2012 Current version: 0.04 Versioning I’ve had comments on my (continued) use of the name “Borland”. Let me take this oppurtunity to explain that when I say “Borlanbd” I mean Borland/Inprise/Devco/Codegear/Embarcadero, since I (still) use products that were release under all these names. A lot has happened since the original version. Kylix can be considered dead for all practical purposes nowadays, but with XE2 Borland ventures again into multi-platform land. Tiburon will have a gigantic impact on anything that handles string. The new 2.6.x series is much more Delphi compatible, and the 2.7.x series (trunk) is absorbing Unicode Delphi features. v0.01 The original (2005) version without a version number. v0.02 Updated in 2008 v0.02b minor updates in September 2009 v0.03 Additions during summer 2010 v0.04 Small updates february 2012 1 Introduction There is a lot of (Object) Pascal code available on the web, usually for Turbo Pascal and Delphi. Since Free Pascal supports both these dialects, most code should in theory be recompilable with FPC (and to a lesser degree with other compilers with the appropiate Borland mode). The main showstopper problems are a too big dependancy on dos and 16-bit functionality (TP/BP), or on the Visual part of the VCL (Delphi ). A lot of Delphi code is also too Windows dependant for use on other platforms, but this (the Windows dependance) is no real long term problem for FPC/win32.
