Features[ edit ] Object-oriented programming uses objects, but not all of the associated techniques and structures are supported directly in languages that claim to support OOP.
SQL SQL structured query language is a language for specifying the organization of database s collections of records. Databases organized with SQL are called relational because SQL provides the ability to query a database for information that falls in a given relation.
It was intended to be easy to learn by novices, particularly non-computer science majors, and to run well on a time-sharing computer with many users. It had simple data structures and notation and it was interpreted: Its recent forms have adopted many of the data and control structures of other contemporary languages, which makes it more powerful but less convenient for beginners.
Pascal About Niklaus Wirth of Switzerland designed Pascal to teach structured programming, which emphasized the orderly use of conditional and loop control structures without GOTO statements.
User-defined data types allowed the programmer to introduce names for complex data, which the language translator could then check for correct usage before running a program.
It was available on nearly all computers, and, because of its familiarity, clarity, and security, it was used for production software as well as for education. The name came from an early project to program a turtlelike robot.
Together with recursive routines, this technique made it easy to program intricate and attractive patterns. Object-oriented languages Object-oriented languages help to manage complexity in large programs. Objects package data and the operations on them so that only the operations are publicly accessible and internal details of the data structures are hidden.
This information hiding made large-scale programming easier by allowing a programmer to think about each part of the program in isolation. Such an object hierarchy made it possible to define specialized objects without repeating all that is in the more general ones. Another influential object-oriented language was Smalltalkin which a program was a set of objects that interacted by sending messages to one another.
It has been one of the most important languages for both education and industrial programming. Ada Ada was named for Augusta Ada King, countess of Lovelacewho was an assistant to the 19th-century English inventor Charles Babbageand is sometimes called the first computer programmer.
Ada, the language, was developed in the early s for the U. Department of Defense for large-scale programming. It combined Pascal-like notation with the ability to package operations and data into independent modules. Its first form, Ada 83, was not fully object-oriented, but the subsequent Ada 95 provided objects and the ability to construct hierarchies of them.
While no longer mandated for use in work for the Department of Defense, Ada remains an effective language for engineering large programs. In particular, Java dispensed with lower-level features, including the ability to manipulate data addresses, a capability that is neither desirable nor useful in programs for distributed systems.
In order to be portable, Java programs are translated by a Java Virtual Machine specific to each computer platform, which then executes the Java program.Learning Object Oriented Programming in C++.

Object-oriented programming language (OOPL) is a high-level programming language based on the object-oriented programming (OOP) model.
OOPL incorporates logical classes, objects, methods, relationships and other processes with the design of software and applications. Special Interest Group on Programming Languages.

Object-oriented programming (OOP) refers to a type of computer programming (software design) in which programmers define not only the data type of a data structure, but also the types of operations (functions) that can be applied to the data structure. In this way, the data structure becomes an. Learning Object Oriented Programming in C++.
