What is c plus plus called object oriented programming language?
C++ is an extension of C; object-oriented capabilities - basically, the possibility of defining classes and of creating objects based on those classes - have been added to the original C.C++ is an extension of C; object-oriented capabilities - basically, the possibility of defining classes and of creating objects based on those classes - have been added to the original C.C++ is an extension of C; object-oriented capabilities - basically, the possibility of defining classes and of creating objects based on those classes - have been added to the original C.C++ is an extension of C; object-oriented capabilities - basically, the possibility of defining classes and of creating objects based on those classes - have been added to the original C.
What have been the strongest influences on programming language design over the past 50 years?
Object oriented analysis and design.
How skinny can a tornado be at the ground?
Tornadoes have been recoded as narrow as 3 feet.
How visual basic.net become object oriented programming?
Visual Basic has always been an object oriented language. VB.NET is no different, but it also conforms to the Microsoft Common Language Infrastructure (CLI) which allows VB code interoperate with other CLI languages including C# and J#.
Why object oriented analysis and design useful?
:-- Object-oriented development is not a new technology but it has not had widespread use and is still maturing. Object-oriented analysis starts you on a path that can lead to benefits not only in the analysis process but in subsequent development phases. Proponents of the object-oriented approach list the benefits as an easier way to promote the understanding of a system, reusability of models and programming, modifiability and reduced costs associated with change, and reduced development risk. These benefits lead to a superior method of analyzing business processes and requirements. Finally, because the contemporary view of development is from the object-oriented perspective, object-oriented analysis allows you to take advantage of the contemporary programming languages, operating systems and associated tools. [1 p.215, 16 p.493, 12, 2 p.11] Objects are said to replicate what humans see in real life and, therefore, appeals to human cognition. The object-oriented paradigm views the world as composed of objects with well-defined properties, with objects replicating things in an environment. [19] It is easier to promote a user's understanding when the user is presented with objects describing things found in the normal course of conducting business. For example, it is much easier for accountants to view a system when entities such as customers, checks, invoices and receipts are used. The user can, therefore, better visualize the concepts of the system and assist the analyst in describing the system by focusing on what is to be accomplished rather than focusing on procedures. [12, 16 p.493] Reusability is a desired goal of all development and is based on the reluctance of reinventing something when it has already been invented. Object-oriented development supports this, especially in the concept of abstraction. [3] Abstraction supports continual iterations of analysis until unique objects are found in a class hierarchy. These unique objects inherit characteristics from the higher level classes and this allows you to reuse information from the previously defined classes, eliminating the need to reinvent it. Class structure leads to the development of class libraries that allow the sharing of models and programming throughout a system. The development process can be simplified, from analysis to requirements to implementation, through the use of the building blocks of classes and objects. [12, 18, 3] The use of objects makes it easier to change and modify systems. For example, the year 2000 (Y2K) problem may have been eliminated by identifying a date object within a system and accessing this object when you needed to date an operation. If the date object had the state variables of month, day and year with each defined as two-character variables, the only change that would be necessary to correct the Y2K problem was to change the year state variable of only the date object. No need to examine multiply lines of code or to use significant resources to locate all the processes using a date functionality and the appearance of it in a procedural program. Modification of systems can also be accomplished through adding methods or state variables to objects. Because encapsulation isolates unnecessary methods and messages from other objects, you can add this type of information to an object to allow it to interact with another object. Theoretically, you are changing the system without having an effect on the existing object interactions. [12, 3] The risks associated with the development process are reduced by providing a methodology that promotes understanding of a system, making information easy to use and reuse throughout a system, and developing a system that is easier to modify and change making the maintenance process easier. It helps to reduce the complexity of the analysis and development process.
What is the difference between object oriented model and relational database model?
see the link below http://www.freetutes.com/systemanalysis/sa8-comparison-relational-model-oo-model.html Different database models differ in their representation of relationships. In relational model, connections between two relations are represented by foreign key attribute in one relation that reference the primary key of another relation. Individual tuples having same values in foreign and primary key attribute are logically related. They are physically not connected. Relational model uses logical references. In object oriented model, relationships are represented by references via the object identifier (OID). This is in a way similar to foreign keys but internal system identifiers are used rather than user-defined attributes. The Object Oriented model supports complex object structures by using tuple, set, list, and other constructors. It supports the specification of methods and the inheritance mechanism that permits creation of new class definitions from existing ones. In relational model, each base relation is implemented as a separate file. If the does not specify any storage structure, most RDBMS will store the tuples as unordered records in the file. It allows the user to specify dynamically on each file a single primary or clustering index and any number of secondary indexes. It is the responsibility of user to chObject Orientedse the attributes on which the indexes are set up. Some RDBMSs give the user the option of mixing records from several base relations together. It is useful when related records from more than one relation are often accessed together. This clustering of records physically places a record from one relation followed by the related records from another relation. In this way the related records may be retrieved in most efficient way possible. Object Oriented systems provide persistent storage for complex-structured objects. They employ indexing techniques to locate disk pages that store the object. The objects are often stored as byte strings, and the object structure is reconstructed after copying the disk pages that contain the object into system buffers. Relational model has keys, entity integrity, and referential integrity. The constraints supported by Object Oriented systems vary from system to system. The inverse relationship mechanism supported by some Object Oriented systems provides some declarative constraints. There are languages such as SQL, QUEL, and QBE are available for relational systems. These are based on the relational calculus. In Object Oriented systems, the DML is typically incorporated into some programming language, such as C++. Hence, the structures of both stored persistent objects and programminglanguage transient objects are often compatible. Query languages have been developed for Object Oriented databases. Work on a standard Object Oriented model and language is progressing, but no complete detailed standard has emerged as yet.
What object has been studied by scientists to reveal history about your solar system?
Everything in the Solar system. Some examples: comets, asteroids, meteorites, planets...
What is pure object oriented language?
Object-oriented (OO) applications can be written in either conventional languages or OOPLs, but they are much easier to write in languages especially designed for OO programming. OO language experts divide OOPLs into two categories, hybrid languages and pure OO languages. Hybrid languages are based on some non-OO model that has been enhanced with OO concepts. C++ (a superset of C), Ada 95, and CLOS (an object-enhanced version of LISP) are hybrid languages. Pure OO languages are based entirely on OO principles; Smalltalk, Eiffel, Java, and Simula are pure OO languages.Reference: Tokar, Joyce L. "Ada 95: The Language for the 90's and Beyond."" According to me JAVA is not a pure oop Language ,because java contains primitive datatypes that's not an Objects."SmalltalkEiffeljavaa programming language that includes all the oops concepts i,e object, class , inheritance,abstraction, encapsulation, data binding, and message passing is called a completely object oriented programming.. example:java.
How many planet is struenis a way from the sun?

What is the name of Neptune's coldest moon?
Triton. It is the coldest object that has been measured in our Solar System, with a temperature of -235° C (-391° F).
Definition of dangling pointer object?
A dangling pointer occurs when objects have been deallocated or deleted from the system. They 'dangle' due to the pointer's values still remaining leaving a location to the non-existent object in the memory.
The differences in voting patterns between men and women have been shown to be?
Women are more likely to vote than men, and they tend to vote for different political parties and candidates. Research has also shown that women are more likely to prioritize certain issues like healthcare and education, whereas men prioritize issues like the economy and national security.
