Preface to the Fifth Edition It is mid 2004. World has left behind the DOTCOM bust, 9/11 tragedy, the economic downturn, etc. and moved on. Countless Indians have relentlessly worked for close to two decades to successfully establish “India” as a software brand. At times I take secret pleasure in seeing that a book that I have been part of, has contributed in its own little way in shaping so many budding careers that have made the “India” brand acceptable. Computing and the way people use C for doing it keeps changing as years go by. So overwhelming...

...Object oriented programming refers to a method of programming in which individual objects, usually called "methods" and "functions", are created and used in junction with each other to perform a function. These objects are organized within the program through use of things called structures or classes. A class is something we use to create a blueprint of sorts for a assortment of variables and components. Similarly, a structure serves the same purpose. The only difference between a structure and a class is that a structure's members are public by default and a classes members are private by default. Another form of "blueprint" used by programmers is the data union. While a union is very primitive in comparison to a structure or class, it is a good tool to use to conserve memory in larger applications. A union uses the same memory block for multiple variables at different points. While two variables in a union cannot be accessed at the same time, a union is a good way to re-use blocks of memory that would normally be left void after a variable is finished with. Now that I have covered the basic points of classes, structures and unions, I will go into more detail of just how powerful a class or structure can be. In basic reference, a class is simply a blueprint to something we create instances of later in the program. This is a very vague statement however, because in object-oriented programming the class is the backbone of the program. It is what makes the...

...To: Rosemary Worth From: Re: misplaced trust on Kate Hoffman causing money loss issue Date: September 17, 2012 This memo is in response to your questions concerning money loss issue raised by Kate Hoffman and any related operating problems. After an in depth study of your company’s daily operation procedure and a situation that you are unable to step in a managerial role because of family responsibilities, I suggest you hire a new manager to take care of daily operation management, focus on 3-4 popular classes, shorten opening hours, and base commissions on performance. My suggestion is based on obtaining better management controls in the following three aspects. People Controls You trust Kate Hoffman so much that you let her take multiple tasks such as marketing, facility up-keeping, scheduling of appointments and record keeping. Kate was paid a salary plus a commission based on gross revenues just as other instructors. Kate might have thought that she did more work than other instructors and deserved more commission. When her expectation was not met, she lacked the motivation to handle multiple tasks and turned to an unethical way – stealing money from unrecorded revenue. If a new manager is hired, Kate can be released from administrative work and concentrate on her instructor job. Thus, further money loss can be avoided, and you can still keep the friendship between Kate and you as before. Furthermore, the newly hired manager can take place of the part time clerical...

...structured programming and data structuring. 2) SQL (Structured Query Language) designed by, Donald D. Chamberlin, and Raymond F. Boyce. The motivation behind this language was designed for managing data held in a relational database management system. ( RDBMS) 3) C, Designed by Dennis Ritchie. the motivation behind this language is structured programming and allows lexical variable scope and recursion. 4) Applesoft BASIC, developed by Marc McDonald, and Ric Weiland. The motivation with this language was it was designed to be backwards-compatible with integer BASIC and used the core of Microsoft’s 6502 BASIC implementation. 5) GRASS, Developed by Thomas A. DeFanti. GRASS is similar to BASIC in sytax, but added numerous instructions for specifying 2D object animation, including scaling, translation, rotation and color changes over time. 1980’s 1) BASICA, Designed by Thomas E.

...Reusability of Code To be able to compare and contrast procedural programming modules and object-oriented programming, or OOP for short, we need to understand the two different styles. Procedural programming was the most commonly used programming language early on with a top-down model. This programming module places its attention on procedures or actions, which take place within the program. A few examples of procedural programming are FORTRAN and BASIC. OOP although has become the preferred method of use. OOP focuses on objects, which are self-contained unit containing date and data operations. When it comes to the reusability of codes OOP makes this task much easier. As procedural programming is a line-by-line programming style as if to be writing out simple instructions. OOP however allows the programmer to utilize inheritance. Inheritance gives the programmer the ability to create new classes, known as subclasses, based on an existing class, known as the superclass. This ability enables the programmer to utilize the data and methods of the original class or superclass. This whole process is where the programmer is able to utilize code that already was written saving them time and eliminating the opportunity for programming errors. Another benefit to OOP over procedural programming is security and the ability to hide code. Within OOP, the programmer is able to label certain data fields as private. Once these data fields are labeled as private, their data and methods...

...ArrayList Johnnie L. Bagley III PRG/420 October 09, 2013 Dr. Orenthio K. Goodwin ArrayList The differences between the Array and an ArrayList is a common question asked by beginners, just starting to code using Java. The Array and ArrayList are both used to store elements, which can be a primitive or an object in the case of ArrayList in Java. A main difference between the ArrayList and an Array in Java would be the static nature of the Array, but the ArrayList has a dynamic nature. Once an Array is created, programmers cannot change the size of it, but an ArrayList will be able to re-size itself at any time. There is one more notable difference between ArrayList and an Array (Paul, 2012). The Array is a core part of Java programming that has a special syntax and a semantics support within Java. An ArrayList is a part of the collection framework of popular classes, such as HashMap, Hashtable, and Vector. There are six more differences between Array and ArrayList which will be listed in numeral order: 1. First and Major difference between Array and ArrayList in Java would be that Array is a fixed length data structure, while ArrayList is a variable length collection class. 2. Another difference is that an Array cannot use Generics, due to it cannot store files, unlike the ArrayList that allows users to use Generics to ensure storage. 3. Programmers can compare the Array vs. ArrayList on how to calculate length of Array or size of an ArrayList. 4....

...PHP Tutorial - Learn PHP If you want to learn the basics of PHP, then you've come to the right place. The goal of this tutorial is to teach you the basics of PHP so that you can: • • • Customize PHP scripts that you download, so that they better fit your needs. Begin to understand the working model of PHP, so you may begin to design your own PHP projects. Give you a solid base in PHP, so as to make you more valuable in the eyes of future employers. PHP stands for PHP Hypertext Preprocessor. PHP - What is it? Taken directly from PHP's home, PHP.net, "PHP is an HTML-embedded scripting language. Much of its syntax is borrowed from C, Java and Perl with a couple of unique PHP-specific features thrown in. The goal of the language is to allow web developers to write dynamically generated pages quickly." This is generally a good definition of PHP. However, it does contain a lot of terms you may not be used to. Another way to think of PHP is a powerful, behind the scenes scripting language that your visitors won't see! When someone visits your PHP webpage, your web server processes the PHP code. It then sees which parts it needs to show to visitors(content and pictures) and hides the other stuff(file operations, math calculations, etc.) then translates your PHP into HTML. After the translation into HTML, it sends the webpage to your visitor's web browser. PHP - What's it do? It is also helpful to think of PHP in terms of what it can do for you. PHP will allow you to: ...
