When you look for the successor of the C language, then you will find C++ and if you are familiar with the C language and want to upgrade yourself in the world of programming, then C++ programming is right for you.

Now, this C++ tutorial gives you a detailed overview of the basic and advanced concepts of C plus plus So, if you are a college student or a working professional, bookmark this C ++ programming tutorial to upscale your CPP programming skills. But before going in-depth with the C Plus Plus tutorial, let’s have a quick intro to C++ language.

What is C++?

C++ is a middle-level programming language that was developed as an extension of the C programming language. In the early 1980s, Bell Labs was an enhancement of the C language to provide support for OOPs (Object Oriented Programming Systems) and additional features.

Print Hello World Program in C++

#include <iostream>int main() { std::cout << "Hello World!" << std::endl; return 0;}

Output

Hello World!

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.

Unlike C, C++ allows exception handling and function overloading. Bringing in the important topics under one roof, this free tutorial to C++ is a very efficient and convenient way to learn C++ from scratch.

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.
