Introduction to C++ Programming Language

C++ is a general-purpose programming language that was developed as an enhancement of the C language to include object-oriented paradigm. It is an imperative and a compiled language.

C++ is a middle-level language rendering it the advantage of programming low-level (drivers, kernels) and even higher-level applications (games, GUI, desktop apps etc.). The basic syntax and code structure of both C and C++ are the same.

Some of the features & key-points to note about the programming language are as follows:

  • Simple: It is a simple language in the sense that programs can be broken down into logical units and parts, has a rich libray support and a variety of data-types.
  • Machine Independent but Platform Dependent: A C++ executable is not platform-independent (compiled programs on Linux won’t run on Windows), however they are machine independent.
  • Mid-level language: It is a mid-level language as we can do both systems-programming (drivers, kernels, networking etc.) and build large-scale user applications (Media Players, Photoshop, Game Engines etc.)
  • Rich library support: Has a rich library support (Both standard ~ built-in data structures, algorithms etc.) as well 3rd party libraries (e.g. Boost libraries) for fast and rapid development.
  • Speed of execution: C++ programs excel in execution speed. Since, it is a compiled language, and also hugely procedural. Newer languages have extra in-built default features such as grabage-collection, dynamic typing etc. which slow the execution of the program overall. Since there is no additional processing overhead like this in C++, it is blazing fast.
  • Pointer and direct Memory-Access: C++ provides pointer support which aids users to directly manipulate storage address. This helps in doing low-level programming (where one might need to have explicit control on the storage of variables).
  • Object-Oriented: One of the strongest points of the language which sets it apart from C. Object-Oriented support helps C++ to make maintainable and extensible programs. i.e. Large-scale applications ca be built. Procedural code becomes difficult to maintain as code-size grows.
  • Compiled Language: C++ is a compiled language, contributing to its speed.

Applications of C++:
C++ finds varied usage in applications such as:



  • Operating Systems & Systems Programming. e.g. Linux-based OS (Ubuntu etc.)
  • Browsers (Chrome & Firefox)
  • Graphics & Game engines (Photoshop, Blender, Unreal-Engine)
  • Database Engines (MySQL, MongoDB, Redis etc.)
  • Cloud/Distributed Systems

Some interesting facts about C++:
Here are some awesome facts about C++ that may interest you:

  1. The name of C++ signifies the evolutionary nature of the changes from C. “++” is the C increment operator.
  2. C++ is one of the predominant languages for the development of all kind of technical and commercial software.
  3. C++ introduces Object-Oriented Programming, not present in C. Like other things, C++ supports the four primary features of OOP: encapsulation, polymorphism, abstraction, and inheritance.
  4. C++ got the OOP features from Simula67 Programming language.
  5. A function is a minimum requirement for a C++ program to run.
