Main Features Of Object Oriented Programming

This situation is more complex since two key object- oriented features, such as polymorphic calls and multiple inheritance, are used at the same time. For TLM2 interfaces the arrangement of both compilers is as follows: • Microsoft Visual C++ 2008 (VC) distributes the information on each inherited class by placing them one next to another. If an inherited class has virtual methods, a pointer to its particular VTABLE is included. Since each interface has only one virtual method, there are four VTABLEs with only one entry pointing to the particular implementation of each method. When a call is made through a base class pointer, tlm fw transport if *p fw in Figure 5, the pointer is adjusted to point to its specific VPTR and class data.

These classes may be user defined classes or predefined classes which are defined library class. Frameworks can be designed from the another framework which will consists of sharing abstract classes in object oriented programming. Source framework is FOIBLE which is implemented based on Model View Controller architecture. Frameworks support reusability concept in object oriented programming. Framework has many advantages in designing part of software development but designing of framework will consists of many abstract classes.

C# provides language constructs to directly support these concepts, making C# a very natural language in which to create and use software components. Several C# features aid in the construction of robust and durable applications: Garbage collection automatically reclaims memory occupied by unused objects; exception handling provides a structured and extensible approach to error detection and recovery; and the type-safe design of the language makes it impossible to have uninitialized variables, to index arrays beyond their bounds, or to perform unchecked type casts. C# has a unified type system. All C# types, including primitive types such as int and double, inherit from a single root object type. Thus, all types share a set of common operations, and values of any type can be stored, transported, and operated upon in a consistent manner.

First, OOP consist of the programming code and data are encapsulated into “an object,” unlike PP where programming code is stored in a place in the system called a “function library” maintenance can be cumbersome. (ATK Solutions, Inc., 2015, para 4) Second, OOP entails information referred to as "class", "instance", "inheritance", and "polymorphism" that empowers the object to be flexible for reuse whereas PP is not as flexible due to its dedication to an itemized task. (ATK Solutions, Inc., 2015, para 5) Two examples of OOP in today’s programming world are Java and Ruby. (Rouse, 2008) Java is intended for use in dispersed applications on business networks and on the Internet. (Rouse, 2008) Ruby is intended for use broadly in Web applications.

Delphi is capeble of using OCX controls, which is a 32-bit OLE-based custom control. Delphi also allows you to create OLE automation servers and clients. These automation objects give you the flexibility of creating programs that perform tasks in the backround and put the results back to your application. Anoter advantage for Delphi is the ability to write multi-threaaded applications. In a multi-tasking enviorment thi is important, as your applications become more comple, it is necessary to execute your applications in seprate pieces, which are called threads.

· Memory Management · This defines how memory is allocated to specific tasks, and how memory is protected from other processes. · Device Interface · Device interfaces define the nature of the peripherals which may be connected to a system, the ease with which new devices are added, the extent to which the full power of a device may be used, and how knowledgeable user programs have to be to work with that device. · File System · The design of the file system is often so closely linked to the kernel design that is often the first indicator of differences between similar operating systems. This can include such simple clues as how files are named, or how directories or folders are named. · Degree of Integration · While some systems attem... ... middle of paper ... ...iles (password, group files) /tmp area for temporary storage, usually cleaned up after reboots, never store important files here Hard Drives, Partitions, CDROM, Network Drives, … · In other operating systems (DOS, Windows, Mac, OS/2) second hard drives, partitions, CDROMS, and network drives are displayed as a separate folder at the same level as the main drive (i.e.

Once simplicity has become apparent to the programmer, a step-by-step procedure is created, through specific and concise programming. Each step represents an important part of the entire program, and must be rendered through exact calculation in-order to reach the programs exact outcome. Large programs may be written through Procedural programming, by using the methodology of breaking down each sections into singular functions. Object-Oriented Programming (OOP) is almost exactly what it sounds like it should be. This type of programming is created through the use of created classes, and created objects within that class.

section{Software Artifacts} An artifact may refer to use cases document, class diagram, or other UML based models; requirements and design document that can help describe the function, architecture and design of software. Some artifacts are utilized to enhance the process of development, such as risk assessment, business cases, project plans etc. These documents are referred in issues, tickets, bug reports or change requests as necessary, thus gaining important role in the analysis of software repositories. section{Integrated Development Environment (IDE)} An Integrated Development Environment or Interactive Development Environment is a software tool specifically developed to provide comprehensive facilities in software development. The most common parts in an IDE are code editor, tools that automate the building process and debugger.

(Rogers, 2014) Encapsulation is used to hide the values or state of a structured data object inside a class, preventing unauthorized parties' direct access to them. 1.3. Characteristics of object oriented programming language i. Classes & Objects A class is simply a representation of a type of object. It is the blueprint, or plan, or template, that describes the details of an object.

Object Oriented Programming OOP is a programming language model organized around Objects rather than "actions" and data rather than logic. a program has been viewed as logical procedure that takes input data and processes it, and return the output data. The programming challenge is how to write logic, not how to define the data. OOP takes the view what we really care about are the objects we want to manage a bit than the logic required to manage them. The first step in Object Oriented Programme is to identify all the objects the programmer wants to mange and how they relate to each other, an exercise often known as data modelling Once an object has been classify, it is generalized as a class of objects.
