  1. CSEObject Oriented Programing Let’s explore and move to “Better C” Lecture #0

  2. Course objectives • To understand basic programming constructs and use the newly acquired skills to solve extensive programming problems. • To understand the principles of the object-oriented model and its implementation in the ‘C++' language. • To build on the concepts learned in C language and use the power of object oriented programming to develop software applications. • To enable the students to write and execute well structured 'C++' programs. • To use problem solving and program design techniques effectively to generate applications.

  3. The hitch… • The BURNING questions in mind… • Oh no… Why another Programming Language ? • What would we do with it, we already know C? • Will it really help improve my programming skills?

  4. A Better C • C++ • Improves on many of C's features • Has object-oriented capabilities • Increases software quality and reusability • Developed by BjarneStroustrup at Bell Labs • Called "C with classes“ an enhanced version of C • Superset of C • Can use a C++ compiler to compile C programs • Gradually evolve the C programs to C++ Towards better programming….

  5. Overview of topics unit wise • Unit I: Concepts and Basics of C++ Programming,Functions and Input/output Streams, Array • Unit II: Pointers, Reference Variables and String Concepts • Unit III: Structured Data Types and Classes, Operator Overloading and Type Conversion

  6. Course contents • Unit IV: Inheritance and Aggregation, Dynamic Memory Management • Unit V : Polymorphism and Data File Operations • Unit VI: Templates and Exception Handling, The Standard Template Library

  7. Unit I:Console based Input/Output Bring in through cin and Take out through cout

  8. Unit I (Continued): Function and Array

  9. Unit II:Pointers and Strings Here you will study about different types of pointer. • Null pointer • Wild pointer • Void pointer • Dangling pointer • This pointer….

  10. Unit III: SDT,Operator Overloading & Type Conversion Look around you and identify some objects Everything is an OBJECT

  11. Object ,Object and Object A student, a professor A desk, a chair, a classroom, a building A university, a city, a country A subjects such as Physics, Math, History, …

  12. Let us explore about LPU • LPU is defined by the interactions among various objects: • Students • Professors inside LPU • Staff • Board governance • State governance outside LPU • … ...

  13. Daily Analysis • In real world, many objects are of same kind.

  14. Encapsulation

  15. Hidden reality sometimes in daily analysis • If you want to know about anything like places to be visited in Jalandhar then what will you do? You simply text that in Google search Box

  16. Reuse, Reduce & Reliable !!! Existing Features Existing Features + Additional Features

  17. Hiding Details

  18. Unit IV: Inheritance But Mummy, where did my blue eyes come from?

  19. Unit V: Polymorphism In front of father In class In CCD One thing and many forms

  20. Polymorphism (continued)

  21. Unit VI: Exception Handling

  22. Next Class: Concepts and Basics of C++ programming Any Question?
