Thinking Object Oriented

By -




Object Oriented (OO) Programming is a programming paradigm that uses objects and interactions between them to design and implement software applications and computer programs. In the OO programming model, a program is a collection of interacting objects. Each object normally encapsulates data and operations that operate on the data. In contrast, in the conventional programming model, which is affected by the von Neumann computer architecture, a program is a list of subroutines or procedures or functions, which are composed of assignment statements, loops, and/or conditional if-else statements, etc. In this conventional procedural model, data and operations are separate. It is hard to structure code effectively to develop software applications when complexity reaches a certain level. Objects in OO programming are still machinelike, but they could be smart by careful design and implementation. Each object knows things, does things, and makes decisions. Each object potentially collaborate with others. Objects motivate reuse of code as well as concepts, which allows building large-scale applications based on blocks of code more economically.

Thinking Object-Oriented is the real power of OO programming. By thinking and approaching a problem using OO programming paradigm, we could see a program in terms objects and interactions between objects, which is similar to the way we think and model the real-world around us. We can map the objects and relationships in the mini-world at which we are interested into interacting objects in a computer program. We certainly do OO thinking all the time even though we might not call it OO thinking.

The languages we speak will direct the ways we think. OO programming languages such as JAVA, C#, Python facilitate thinking OO in programming. However, we do need to know that we can develop procedural programs using imperative programming languages such as C to solve the problems as well.

25 Google Interview Questions

1 Prepare Before Your Interview Do you prepare before your interview at Google? Of course you will. But how and where to start? This report will provide you a list of 25 questions collected from Web provided by Google interview candidates. The list of questions is focus on CS fields. 2 Questions The question listed as follows are not ordered based on any criterion. The programming languages are required to be used are usually not specific. You can practice using Java, C++, C, C#, etc. For each problem, you need figure out at least one solution. If there are multiple solutions to the problem, make sure you understand how to analyze the efficiency (both time and space). Describe a data structure as well as operations on the data structure. What is the difference between function overloading and overriding? Given a superclass A, a subclass B of superclass A where B overrides a function foo() in A, an instance of class B, how to invoke foo() defined in class A? How to check if tw

Convert LaTeX to HTML

By -
Today I spent quite lots of time to figure out how to convert LaTeX source files to HTML documents. I was trying to install latex2html using fink . The installation of tetex-base failed quite a few times. Eventually I got latex2html installed using fink . Unfortunately, the conversion from my tex files to HTML documents again failed to read document parts. I finally gave up and remove my fink installations from my computer. I then did a few minute google search to use htlatex from TeXShop since I have TeXShop installed in my Macbook. What I did is copy the file htlatex.engine from /Applications/Tex/TeXShop.app/Contents/Resources/TeXShop/Engines/Inactive/TeX4ht/ into folder /Users/ /Library/TeXShop/Engines/ Then, I am able to compile my tex files using htlatex in TeXShop . It works perfect!

Art of Software Development

New York City artist  Nathan Sawaya   exhibited the following art piece of Lego art.  I guess everyone knows to how to connect, manipulate lego pieces.  But only artists like Nathan Sawaya can make such art from the ordinary lego bricks.   We study software development by learning programming languages, tools, methods, ways of thinking, etc.  These topics are normally covered in computing-related curricula.  We also know that experiences are very important ingredient to master programming.  Exactly how all of them work together to upgrade software developers?  What is the journey by which a programmer can reach the mastery of programming or coding and produce art pieces of software?
