CREATION OF C-LANGUAGE: C was invented by Dennis Ritchie in the 1970s at Bells Laboratory. DEC PDP-11 that used the UNIX operating system. 5/18/2019 BY:HIRA FARMAN

CREATION OF C++: C++ was invented by Bjarne Stroustrap beginning in 1979 at bell laboratories in Murray hill, New Jersey. Initially called the new language “C with Classes.” In 1983 the name was changed to C++. C++ contains the entire C language that’s why “C with Class”. C++ runs on a variety of platforms, such as Windows, Mac OS, and the various versions of UNIX. 5/18/2019 BY:HIRA FARMAN

INTRODUCTION TO PROGRAMMING IN C++

Prerequisites: Before you start doing practice with various types of examples given in this reference, I'm making an assumption that you are already aware about what is a computer program and what is a computer programming language? 5/18/2019

INTRODUCTION: A program is a sequence of instructions for a computer to execute. Every program is written in some programming language. The C++(Pronounced “see-plus-plus”) language is one of the newest and most powerful programming languages available. It allows the programmer to write efficient ,structured, object oriented programs. 5/18/2019

Need for a New Language: Introduced C++ as a new programming language to address the problems posed by traditional languages. It is a completely new platform for developing the next generation of Console Application 5/18/2019 BY:HIRA FARMAN

The focus of Oop language is not on structure but on modeling data. 5/18/2019 BY:HIRA FARMAN

Programmers code using “blueprints” of data models called classes. 5/18/2019 BY:HIRA FARMAN

Use of C++: C++ is used by hundreds of thousands of programmers in essentially every application domain. C++ is being highly used to write device drivers and other software's that rely on direct manipulation of hardware under real-time constraints. Anyone who has used either an Apple Macintosh or a PC running Windows has indirectly used C++ because the primary user interfaces of these systems are written in C++. 5/18/2019

Standard Libraries: Standard C++ consists of three important parts: The core language giving all the building blocks including variables, data types and literals, etc. The C++ Standard Library giving a rich set of functions manipulating files, strings, etc. The Standard Template Library (STL) giving a rich set of methods manipulating data structures, etc. 5/18/2019

WHAT IS OOP: OOP allows decomposition of a problem into a number of entities called objects and then builds data and functions around these objects. The software is divided into a number of small units called objects. The data and functions are built around these objects. The data of the objects can be accessed only by the functions associated with that object. The functions of one object can access the functions of another object. 5/18/2019 BY:HIRA FARMAN

DISCUSSION : BY:HIRA FARMAN

What is Object-Orientation? A technique for system modeling. OO model consists of several interacting objects 5/18/2019 BY:HIRA FARMAN

What is a Model? A model is an abstraction of something. Purpose is to understand the product before developing it . 5/18/2019 BY:HIRA FARMAN

Examples –Model Highway maps Architectural models Mechanical models 5/18/2019 BY:HIRA FARMAN

5/18/2019 BY:HIRA FARMAN

Example – OO Model Interactions Objects Abu Bakar drives House Car Tree Interactions Abu Bakar lives in the house Abu Bakar drives the car 5/18/2019 BY:HIRA FARMAN

Object-Orientation – Advantages: People think in terms of objects. OO models map to reality. Therefore, OO models are : easy to develop easy to understand 5/18/2019 BY:HIRA FARMAN

What is an Object? An object has: State (attributes) Well-defined behaviour (operations) Unique identity 5/18/2019 BY:HIRA FARMAN

Example –Ali is a Tangible Object State (attributes) -Name -Age behaviour (operations) -Walks -Eats Identity -His name 5/18/2019

Example – Car is a Tangible Object: State (attributes) - Color -Model behaviour (operations) - Accelerate - Start Car Change Gear Identity - Its registration number 5/18/2019

In order to clearly understand the object orientation model: let’s take your “hand” as an example. The “hand” is a class. Your body has two objects of the type "hand", named "left hand" and "right hand". Their main functions are controlled or managed by a set of electrical signals sent through your shoulders (through an interface). So the shoulder is an interface that your body uses to interact with your hands. The hand is a well-architected class. The hand is being reused to create the left hand and the right hand by slightly changing the properties of it. 5/18/2019
