History of C++

Basically, the concept of C++ is introduced in the early ’80s (1982) by a software engineer Bjarne Stroustrup was doing work for his Ph.D. thesis in AT& T Bell Labs(American Telephone& Telegraph), located in Murray Hills, NewJersey, USA

Definition of C++: According to Stroustrup C++ is a general-purpose, high-level, compiler based and objected oriented Programming language

Stroustrup is very interested in C language because of its powerful features like –

Multipurpose programming,
Portability
Pointers
Dynamic memory allocation,
Midlevel flavor…

Motivation from Simula67

The Major disadvantage of C language is, data is freely moving around the functions.
Due to this, It is not able to design super secure applications because of the absence of data hiding features
To avoid this problem the concept of classes is added to traditional C language which was picked from Simula67
Hence It was named as C with classes initially

Naming as C++

Initially, people call this language as

C with classes
Superset of C
Extension of C
Advanced version of C
Increment of C and many names…

To avoid this confusion in 1983 it was renamed as C++ from C with classes

The increment(++) operator in its name: It indicates that C++ is an extension of C language. due to this all the operators, data types, functions can be used in C++ as well

Newly added keywords and exclusively in C++

asm	dynamic_cast	namespace	reinterpret_cast
bool	explicit	new	static_cast
catch	false	operator	template
class	friend	private	this
const_cast	inline	public	throw
delete	mutable	protected	true
try	typeid	typename	using
using	virtual	wchar_t

Object-Oriented Programming

C++ main objective is to mix the flavors of data hiding with C to design super secure applications
Object Oriented programming is a programming style that is associated with the concept of Class, Objects and various other concepts revolving around these two, like Inheritance, Polymorphism, Abstraction, Encapsulation etc.
These ideas made C++ powerful to design both enterprise and system applications
