1. PROGRAMMING WITH C ++

2. WHAT IS A LANGUAGE & WHY WE NEED

3. PROGRAMMING LANGUAGES:
BASIC
COBOL
PYTHON
FORTRAN
LISP
PASCAL
ADA
PERL
RUBY
PROLOG
SCIENTIFIC & ENGINEERING PURPOSE

4. ANSI----->AMERICAN NATIONAL STANDARD INSTITUTE
ALGOL-60
CPL
BCPL----> MARTIN RICHARDS
B---> KEN THOMPSON
C LANGUAGE

5. INTRODUCTION TO C , C++
C LANGUAGE WAS DESIGNED BY “DENNIS RITCHIE IN 1972 at AT & T BELL LABORATORIES
C IS A STRUCTURED PROGRAMMING LANGUAGES
IT IS USED TO DESIGN DIFFERENT APPLICATIONS
C ++ IS AN EXTENSION OF C LANGUAGE
C ++ WAS DESIGNED BY “BJARNE STROUSTRUP” IN 1980

6. IT IS MACHINE DEPENDENT LANGUAGE C++ IS 00PS( S---> SYSTEM)
DENNIS RITCHIE
BJARNE STROUSTRUP

7. APPLICATIONS OF C ++
WHEN ANY NEW FEATURE IS NEEDED TO IMPLEMENT, VERY EASY TO ADD TO EXISTING STRUCTURE
C ++ WILL REPLACE C-LANGUAGE IN FUTURE

8. FEATURES OF OOPS

9. OBJECT AN OBJECT WHICH EXISTS PHYSICALLY IN THE WORLD
AN OBJECT WILL HAVE BEHAVIOUR
BEHAVIOUR IS REPRESENTED BY PROPERTIES & ACTIONS
EX: human
NAME, AGE GENDER
PROPERTIES
WALK, TALK, DANCE, SING
ACTIONS

10. CLASS A CLASS IS A MODEL OR A PLAN TO CREATE AN OBJECT
A CLASS IS A BLUE PRINT OF AN OBJECT

11. CLASS & OBJECT

12. INHERITANCE CREATING A NEW CLASS FROM AN EXISTING CLASS.
TEACHER
EMPLOYEE
PRINCIPAL
DEAN
INCHARGE

13. DATA ABSTRACTION DATA ENCAPSULATION
HIDING UNNECESSARY INFORMATION FROM THE USER & GIVING RELEVANT DATA.
DISPLAYS THE INFORMATION WHEN THE USER REQUESTS.
DATA ENCAPSULATION

14. ABSTRACTION & ENCAPSULATION

15. POLYMORPHISM
IT IS CAME FROM 2 GREEK WORDS WHICH MEANS “ MANY FORMS ”.

16. DYNAMIC BINDING
IT MEANS A BLOCK OF CODE WILL BE EXECUTED WHENEVER A USER CALLS.
IT IS ALSO CALLED AS “dynamic-dispacth”, “late binding”, “runtime binding”.

18. STRUCTURE OF C++ DOCUMENTATION SECTION //--------------------
/* */
LINKING SECTION >HEADER FILES
DEFINITION SECTION--->TO DECLARE SYMBOLS
MAIN FUNCTION > LOGIC
TO GIVE COMMENTS

19. WORKING WITH C++ TO WORK WITH C++ WE NEED AN EDITOR: TURBO C++
We need an editor to type, save, open, compile & to run a program
Double click this icon on desktop
To start c + + programming

20. WE WILL SEE two small PROGRAMs IN C++

21. AFTER WRITING THE PROGRAM WE HAVE TO COMPILE THE PROGRAM TO CHECK ERRORS.
AFTER COMPILATION WE NEED TO RUN THE PROGRAM FOR OUTPUT.
RUN >
ALT + F9
ALT + F5
CTRL + F9

22. #INCLUDE<IOSTREAM.H>:
# > PREPOSESSOR
INCLUDE-----> INCLUDING IOSTREAM FILE
IOSTREAM------> IOSTREAM IS AN HEADER FILE THAT CONTAINS FILES LIKE: INPUT & OUTPUT STATEMENTS.
EVERY C++ PROGRAM SHOULD HAVE ONE HEADER FILE.
MAIN(): EVERY C++ PROGRAM SHOULD HAVE ONE MAIN(), THE PROGRAM EXECUTION STARTS FROM MAIN().

23. OUTPUT OPERATOR: COUT----->TO PRINT
<< > INSERTION OR PUT TO OPERATOR.
INPUT OPERATOR:
CIN---> TO TAKE INPUT
>>-----> EXTRACTION OPERATOR

24. RETURN TYPE: EVERY C++ PROGRAM SHOULD END WITH RETURN 0
RETURN TYPE: EVERY C++ PROGRAM SHOULD END WITH RETURN 0. OTHERWISE, IT GIVES YOU A WARNING.
CASCADING I/O OPERATOR: WE CAN USE THE INSERTION OPERATOR (<<) TWO TIMES IN A SINGLE STATEMENT.
