SOFTWARE A software is a collection of programs. Types of software : Application Software (VB) and System Software (C and C++) A program is a set of instructions Instruction means command.

C C Program was developed by Dennics Rictic in the year 1980. C is a structured oriented programming (or) Procedure Oriented Programming (POP).

C TERMS Data – A Collection of information. Function – To stored the group of statements. It returns only one value.

C++ C++ was developed by Bjarne Stroustrup in the year 1983. C++ is a Object Oriented Programming (OOP). OOP is an approach, that create a partition memory area for both data and function

C++ TERMS Data - A collection of information Function - It returns only one value. To stored the group of statements. Class - A combination of data and functions. Object - It is instance of class.

HEADER FILE # include <iostream.h> - To stored the input and output statements. # - Preprocessor Include - Keyword Io - Input and Output. Stream - Sequence of bytes. .h - Header file. # include <conio.h> - To stored the clrscr( ) and getch( ) statements. # include<math.h> - To stored the mathematical functions (Sin or Cos etc.,)

CLASS DECLARATION Class classname { private: Data Declaration; public: member function declaration or definition; };

MEMBER FUNCTIONS Member Function Declaration returntype functionname (datatype variablename); Returntype – void or int. Function name – User Defined Name. Datatype - int Variable name - User Defined Name. Member Function Declaration returntype functionname (datatype variablename) {-------; }

main() main ( ) // It returns integer value. { classname object; object.functionname ( ); }  main( ) – It is used to access the public.  public( ) - It is used to access the main ( ) and private.  private( ) - It is used to access the public( ).

EXAMPLE # include <iostream.h> c=a+b; class display cout<<c; { } private: }; int a,b,c; main( ) public: { void dis( ) display d; { d.dis( ); cin>>a>>b; }
