What is the history of object-oriented programming?

What is the history of object-oriented programming?

“Object-Oriented Programming” (OOP) was coined by Alan Kay circa 1966 or 1967 while he was at grad school. Ivan Sutherland’s seminal Sketchpad application was an early inspiration for OOP. It was created between 1961 and 1962 and published in his Sketchpad Thesis in 1963.

When did object-oriented programming started?

Object-oriented programming began with the Simula language (1967), which added information hiding to ALGOL.

When was procedural programming invented?

The first major procedural programming languages appeared circa 1957–1964, including Fortran, ALGOL, COBOL, PL/I and BASIC. Pascal and C were published circa 1970–1972.

What existed before OOP?

Before OOP, the structured programming paradigm used to separate processes and data.

Who introduced oops concept?

In the mid-1980s Objective-C was developed by Brad Cox, who had used Smalltalk at ITT Inc., and Bjarne Stroustrup, who had used Simula for his PhD thesis, eventually went to create the object-oriented C++. In 1985, Bertrand Meyer also produced the first design of the Eiffel language.

Who developed first OOP language?

Actually, SIMULA 1 (1962) and Simula 67 (1967) are the two earliest object-oriented languages. The work on the Simula languages was done by Ole-John Dahl and Kristen Nygaard at the Norwegian Computing Center in Oslo, Norway.

Who created procedural programming?

C is one of the descendants of ALGOL 60. It was developed in 1972 by Ken Thompson and Dennis Ritchie, both of Bell Laboratories. Their goal was to create a language that would combine high-level structured language features with those that control low-level programming.

Why OOPs is better than procedural language?

Security: Object-oriented programming is more secure than procedural programming, because of the level of abstraction or we can say data hiding property. It limits the access of data to the member functions of the same class. While there is no such data hiding in the procedural programming paradigm.

Who developed object-oriented concepts in 1986?

Alan Kay, considered by some to be the father of object-oriented programming, identified the following characteristics as fundamental to OOP Kay 1993 : 1.

Why was OOP invented?

To solve such kinds of problems, OOP, an object-oriented approach was developed as a solution. The OOP concept was basically designed to overcome the drawback of the above programming methodologies, which were not so close to real-world applications. The demand was increased, but still, conventional methods were used.

Which programming language came first?

Computer Programming History: FORTRAN was the first computer programming language that was widely used.

What is the first computer created using object-oriented programming?

The first personal computer created using Object-Oriented Programming is PC DOS by IBM. In 1967, the practice of Object-Oriented Programming started. There are seven programming languages that are categorized in terms of complexity.

Why Oops is better than procedural language?

Why is C known as procedural language?

Answer: C programs follow a procedure of steps written in it, called functions. It follows a top-down approach i.e. much importance is given to flow of program rather than on data on which functions operate.

Can object-oriented programming exist without procedural programming?

You can learn to program in OO without being able to code non-trivial-to-complex programs in procedural languages, but the theoretical bases behind procedural are inevitable.

Is OOP faster than procedural?

OOP requires a lot more memory allocations (MALLOC) and a lot more operations to run in memory than procedural code. It requires a lot more CPU time to perform its tasks. It is essentially ‘overhead’, wrapped around procedural code, adding to the CPU burden to execute it, especially when performing database operations.

What is the history of c language?

A successor to the programming language B, C was originally developed at Bell Labs by Dennis Ritchie between 1972 and 1973 to construct utilities running on Unix. It was applied to re-implementing the kernel of the Unix operating system. During the 1980s, C gradually gained popularity.

What are the advantages and disadvantages of object oriented programming?

OOP software techniques break programs into functional blocks called objects, making frequently needed features such as control buttons, database management and math easier to use and share among programmers. However, the advantages come with tradeoffs such as added software complexity and reduced performance. Advertisement.

What is the difference between object oriented and functional programming?


  • Functional Programming – focus on function evaluation
  • Object-Oriented Programming – focus on the concept of objects
  • Data:
  • Functional Programming – uses immutable data
  • Object-Oriented Programming – uses the mutable data
  • Model:
  • Functional Programming – follows a declarative programming model
  • What are the advantages of procedural programming?

    Procedural Programming is excellent for general-purpose programming.

  • The coded simplicity along with ease of implementation of compilers and interpreters.
  • A large variety of books and online course material available on tested algorithms,making it easier to learn along the way.
  • What is the difference between procedural and imperative programming?
