C++ is an efficient and powerful language and finds wide use in various GUI platforms, 3D graphics and real-time simulations. Because of the inclusion of rich function libraries, working in C++ becomes simpler and convenient than C. Being object-oriented programming like Java, C++ provides the support of inheritance, polymorphism, encapsulation, etc.

C++ Tutorial | Learn C++ Programming - GeeksforGeeks (2)Why to Learn C++ Programming

Here in this section, we have listed some points to teach you why C++ is important and why you should learn this programming language as a coder.

  • C++ supports the principles of OOP (Object Oriented Programming), including classes, objects, inheritance, polymorphism, and encapsulation.
  • C++ is an appropriate programming language for systems programming and performance-critical applications. Basically, C programming supports low-level memory manipulation and direct hardware access.
  • The STL, or Standard Template Library, in C++, provides a collection of template classes and functions for common data structures and algorithms, which helps simplify and accelerate software development.
  • Although C++ is well known for supporting OOP, it also supports procedural and generic programming. This implies that you can write code in a variety of ways, depending on the requirements of your project.
  • The ability to write and compile C++ code to run on different platforms makes it a flexible language for creating cross-platform applications.
  • Developers have the freedom to create their own abstractions thanks to C++’s support for the creation of customized data types and operators.
  • It is widely used in many different fields, such as systems programming, game development, embedded systems, and more. C++ has a sizable and vibrant user community.

Evolution of C Language

To improve the features and libraries, the C language evolved over the years, e.g., C++98, C++11, C++14, C++20, and the latest one, C++23.
