History of C++ Language

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

The Birth of C++

In the early 1970s, Bjarne Stroustrup, a Danish computer scientist, developed a language called “C with Classes” as an extension to the C programming language. Stroustrup aimed to enhance C’s capabilities by adding support for object-oriented programming (OOP) concepts. This new language formed the foundation of what would later become C++.

The Evolution of C++

In 1983, the language was renamed to C++ to reflect the new features and improvements introduced over time. Stroustrup published “The C++ Programming Language,” a book that served as a comprehensive guide to the language and gained widespread popularity among programmers. The evolution of C++ continued with the release of various standards, each bringing new features, optimizations, and bug fixes to the language.

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 the C language because of its powerful features like –

  • Multipurpose programming,
  • Portability
  • Pointers
  • Dynamic memory allocation,
  • Midlevel flavour

Motivation from Simula67 

  • The Major disadvantage of the 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


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

Standardization and Portability

To ensure consistency and compatibility across different platforms, the International Organization for Standardization (ISO) started working on standardizing the C++ language. The first standardized version, known as C++98 or C++03, was released in 1998. Subsequent revisions, such as C++11, C++14, C++17, and the latest C++20, brought numerous improvements, including enhanced language features, libraries, and performance optimizations.

C++’s standardized nature has contributed to its portability, allowing developers to write code that can run on various operating systems and architectures. This characteristic has made C++ a popular choice for building applications ranging from desktop software to embedded systems and game development.

C++ vs. Other Languages

When comparing C++ with other programming languages, several factors come into play. C++ excels in terms of performance, as it allows fine-grained control over system resources. It also provides a low-level programming model that enables developers to optimize code for speed and memory usage.

However, C++ complexity and syntax can be challenging for beginners or developers coming from higher-level languages. Moreover, languages like Python and JavaScript offer faster development cycles and greater simplicity for certain applications.
