ABOUT C++
○ C++ is a programming language○ C++ is a middle-level programming language
○ Developed by Bjarne Stroustrup starting in 1979 at Bell Labs
○ C and C++ become a widely used programming language
○ C++ fully supports object-oriented programming (OOP's).
○ OOP's is a model of programming language. or It is a Concept.
○ C++ is used by thousands of programmers to develop an application .
○ C++ is used to write device drivers and other software's
○ C++ is widely used for research
○ The primary user interfaces of systems are written in C++ (specially for windows and mac).
○Actual C++ compiler, which will be used to compile your source code to executable program.
○Most C++ program extension is name.cpp
○Most used and free available compiler are listed below ...click for download
#include<iostream.h> //header file
int main()
{
cout<<"Hackers Rocks"; // used to display
FEATURE OF C++
○ C++ is Easy to learn and Understand.
○ C++ is usually considered a "multi-paradigm" language.
○ It produces more efficient programs.
○ It can also handle low-level activities as well as high level activities
○ It can be compiled on a variety of computer platforms.
○ C++ is an object oriented programming language therefore it supports
1. Polymorphism (one name and many forms)
2. Encapsulation (wrapping of a data & function in single unit)
3. Data Abstraction ( hiding of data and showing important features)
4. Inheritance (deriving data from one class to another)

4. Inheritance (deriving data from one class to another)
5. Data Banding (communication between objects)
○ C++ is not portable. (means source code is runs anywhere but exe file does not run )

REQUIREMENTS (ENVIRONMENT SET UP)
○Most C++ program extension is name.cpp
○Most used and free available compiler are listed below ...click for download
- Dev C++ (not for begnner)
- Codeblocks
- Turbo C++ and many more..
EXAMPLE OF A C PROGRAM
#include<iostream.h> //header file
int main()
{
cout<<"Hackers Rocks"; // used to display
return 0; // function to returning something.
}
1- Comment:
◘ It is the statement in the programs which compiler ignores.
◘ It increases readability of the program.
◘ Comments are of two type, single line and multi-line comment.
2- Header File:
◘ iostream is a header file.
◘ iostream stands for "Standard input output".
◘ It contains definition of input/output facilities in C programming.
3- Main():
◘ whenever parenthesis " () " are used. It is called function in C programming.
◘ main() function is like the entry point in the program.
4-cout:
◘ cout is also a function.
◘ " << " is called excertion operator.
◘ the definition (work ) of cout is, to display whatever is written after the << and ;(semicolon) .
◘ the definition of cout is given by iostream.h file.
◘ the definition (work ) of cout is, to display whatever is written after the << and ;(semicolon) .
◘ the definition of cout is given by iostream.h file.
After Compilation
When ever you compile your source code ... then the compiler generate 4 types of files
○ name.cpp (source code file)
○ name.bak (back up file)
○ name.txt (normal text file)
○ name.exe (executable file)
all four types of file ...you can find in C Drive --> Program Files-->turbo c++ -->bin --> all files present here....after successful compilation.
