What is C++ Programming Language? An Introduction

C++ Programming Language is a high-level programming language (some consider it as mid-level also) that was developed as a better version of C language. It follows the object-oriented approach. It is regarded as middle level as it is close to low-level programming, suitable for drivers and kernels and even higher-level for applications, desktop applications, games, etc.

In this blog, you will learn from scratch to an advanced level for C++ programming. If you are a newbie, you can easily learn the C++ programming language through this blog, and if you are a professional, then do give a try to the quiz section to test your knowledge.

C++ Programming Language

C++ is widely encouraged for Competitive Programming because of its fast execution and ease to use, and it is a versatile tool for Professional Coders. Some advantages of using C++ programming languages are:

  1. Widely used to code and design architecture for Database Engines like MySql, MongoDB, etc.
  2. Most Browsers are programmed in C++ like Chrome and Firefox.
  3. C++ is encouraged for distributed and Cloud Computing.
  4. Many Graphic Engines and Game Engines uses C++.
  5. Many Operating Systems, as well as software like Microsoft Redistributable and DirectX, are written in C++.

Students are advised to learn C and then C++ first as it gives them a basic idea of any programming language and Data Structures. It is fun in learning C++. Learning C and C++ are almost the same, only the main difference that lies in between them are:

  • C++ has OOPS (Object Oriented Programming) support, emphasising the main features like Abstraction, Polymorphism, Encapsulation, and Inheritance.
  • It requires at least one function like main() for execution.
  • Its syntax are much easier to learn, and hence debugging becomes easy.

Several noteworthy characteristics and essential elements regarding the programming language include the following:

  • Simple: It is a simple language in the sense that programmes may be decomposed into logical units and components, that it supports a large number of libraries, and that it supports a wide range of data types.
  • A C++ executable is not platform-independent (compiled applications on Linux will not execute on Windows), but it is machine-independent.
  • It is a mid-level language since it enables us to develop both systems (drivers, kernels, networking, etc.) and large-scale user applications (Media Players, Photoshop, Game Engines etc.)
  • For quick and speedy development, has comprehensive library support (both standard built-in data structures, algorithms, and so on) as well as third-party libraries (e.g. Boost libraries).
  • Execution speed: C++ applications are very fast. Due to the fact that it is a compiled language, it is also quite procedural. Newer languages provide more built-in default features like garbage collection, dynamic typing, and so on, this might slow down the total execution of the programme. Because C++ has no such added processing cost, it is lightning quick.
  • C++ has pointer support, which enables users to modify storage addresses directly. This is advantageous while doing low-level programming (where one might need to have explicit control over the storage of variables).
  • Object-Oriented: One of the language’s major aspects that distinguishes it from C. Support for object-oriented programming enables C++ to create manageable and expandable applications. That is, large-scale applications may be developed. Maintaining procedural code gets more challenging as the codebase increases in size.
  • C++ is a compiled language, which contributes to its speed.

C++ Applications:

  • C++ is used in a variety of applications, including the following:
  • Operating Systems & Systems Programming, for example, Linux-based operating systems (Ubuntu etc.)
  • Users of browsers (Chrome & Firefox)
  • Engines for graphics and games (Photoshop, Blender, Unreal-Engine)
  • Engines de bases de données (MySQL, MongoDB, Redis etc.)
  • Systems on the Cloud/Distributed
