C++ is a powerful, high-level, object-oriented, general-purpose programming language that was developed by Bjarne Stroustrup at Bell Labs in 1979. It is an extension of the C programming language, with more powerful capabilities and a broader range of applications. C++ is widely used in software development, game development, operating systems, network programming, and web programming. C++ is an object-oriented programming language, meaning that it allows developers to create and manage objects that can be used to store data, and to create and control their behavior. There are many advantages to learning C++, such as its speed, robustness, and flexibility. C++ is also a popular and evergreen programming language, and a great C++ programmer will never lack for work. This C++ tutorial is intended for beginners in programming who want to learn the basics of C++ and gain a better understanding of the language.
What is C++?
C++ is a powerful, high-level, object-oriented, general-purpose programming language that was developed by Bjarne Stroustrup at Bell Labs in 1979. It is an extension of the C programming language, with more powerful capabilities and a broader range of applications.

C++ is an object-oriented programming language, meaning that it allows developers to create and manage objects that can be used to store data, and to create and control their behavior.
Why Learn C++?
C++ is a must-have for any programmer looking to get ahead in their software development career. There are many advantages to learning C++, such as its speed, robustness, and flexibility. C++ is close to the hardware, allowing developers to access low-level operations, as well as allowing for better memory management and improved performance.
C++ also provides a solid foundation for object-oriented programming, allowing developers to gain a better understanding of the implementation of polymorphism, virtual tables, dynamic type identification, and other object-oriented concepts.
C++ is also a popular and evergreen programming language, and a great C++ programmer will never lack for work. Moreover, C++ programming can be quite lucrative, as skilled C++ developers are in high demand and can command a premium salary.
C++ is also widely used in application and system programming, giving developers a wide range of options for developing software in their preferred area of interest. Finally, learning C++ provides a great introduction to the fundamentals of computer programming, such as the differences between compilers, linkers, and loaders, various data types, storage classes, variable types, and their scopes.
Hello World Example in C++
To get you started on your C++ journey, here is a simple Hello World program written in C++. To see the program in action, you can try out the live demo.
#include <iostream>
using namespace std;
// main() is where program execution begins.
int main() {
cout << "Hello World"; // prints Hello World
return 0;
}Compilers
C++ is widely used in a variety of applications, such as application and system programming, games development, programming language development, computation programming, and embedded systems.
Application Software Development – C++ has been used to develop many of the world’s most popular operating systems, such as Windows, Mac OSX, and Linux. It has also been used to develop the core parts of browsers like Mozilla Firefox and Chrome. C++ has also been used in the development of the popular MySQL database system.
Programming Language Development – C++ has been used in the development of many new programming languages, such as C#, Java, JavaScript, Perl, UNIX’s C Shell, PHP, Python, and Verilog.
Computation Programming – C++ is a popular choice for scientists and engineers due to its speed and computational efficiency.
Games Development – C++ is extremely fast, allowing programmers to use procedural programming for CPU-intensive functions and giving them greater control over hardware. As such, it has been widely used in the development of gaming engines.
Embedded Systems – C++ is used extensively in the development of medical and engineering applications such as software for MRI machines and high-end CAD/CAM systems.
