An Overview of C++ Programming

1. Objective

• History Of  C++

• Fact

• Features Of C++

2. History Of C++

• Bgarne Stroustrub

• 1979

• At&T'S Bell Labs

• C with Classes

• 1983 (C++)

3. Facts Of C++

• C++ 's OOps aspects was inspired by a computer simulation language called simula67.

• Java is written in C++

• Major operating system of modern times are written in C++

• C++ is words 4th most used programming language

4.

Features of C++

• C++ is a middle level language.

• C++ support's principal of objects oriented paradigm.

• C++ joins three separate programming tradition represented by c. The object oriented language tradition represented by the class enhancement C++ add to C.

• Generic programming supported by C++ template's.

5. Comparison Between C & C++

• C++ is a super set of C language .

• C++ program can use existing C software libraries.

• C follows top down approach of programming .

• C++ follows bottom up approach of lrogrprogra.

• C adopts procedure oriented programming language

6. Object Oriented Programming (OOP)

• Oops is Programming approach which revolves around the concept of "objects".

• "An entity in the system that can be defined as a set of properties and set of operation performed using entity properly set is known as object".

• Encapsulation

• Data hiding

• Abstraction

• Polymorphism

• Inheritance

7. Class  And Object

• Class is a blueprint of an object.

• Class is a description of objects property set and set of operation.

• Creating class is as good as defining a new data type .

• Class is a means to achieve encapsulation.

• Object is an instance of class.

8. Class Vs Object

9. Class box⟵(data type)

10. {

11. int l,b,h; /* variable in C but here object in C++ \*

12. void set dimension(int X ,int y ,int z)

i. ⇖(function)

13. {........}

14. void showDimension()

1. ⇖(function)

15. {........}

16. };
