Học C++ từ Cơ Bản đến Nâng Cao với C++ Hiện Đại

This course contains the use of artificial intelligence.

Whether you want to start coding for a new career, pursue a part-time hobby, or simply enhance your current role, the first step is deciding which programming language to learn. C++ is one of the most widely used programming languages across the industry. In fact, many video games, embedded systems, IoT devices, and resource-intensive AI applications are built using C++. Because of its widespread use in the programming world, C++ is recognized as one of the best programming languages you can learn.

Advantages of C++ Over Other Languages

• Object-Oriented Programming (OOP): Unlike the C programming language, C++ supports the Object-Oriented Programming (OOP) paradigm. This makes code organization, reuse, and maintenance much easier compared to purely procedural programming.

• Speed: When performance is a critical factor, C++ is often the preferred choice. Programs written in C++ are compiled directly to machine code, resulting in significantly faster execution compared to most general-purpose programming languages.

• Compilation: Unlike interpreted languages, C++ code must be compiled into low-level machine code before execution, which contributes to its high performance and efficiency.

• Rich Library Support: One of the strongest advantages of C++ is its extensive library ecosystem. Since the foundations of C++ date back to the late 1970s and early 1980s, it offers a vast collection of mature and well-tested libraries that can be used for a wide range of purposes.

• Pointer Support: C++ supports pointers, allowing direct memory access and efficient resource management—features that are limited or unavailable in many other programming languages.

• Closer to Hardware: C++ operates closer to hardware than most general-purpose programming languages. This makes it especially useful in scenarios where low-level control and close interaction between software and hardware are required.

  
  

C++ Usage Areas (Real-World Applications)

Almost all programs and systems you use today—or at least parts of their codebases—are written in C or C++. Whether it is an operating system, a web browser, a video game, or video editing software, C++ applications can be found nearly everywhere. Below are some of the most common areas where C++ is widely used:

• Operating Systems: C++ supports both procedural and object-oriented programming paradigms. It is powerful, fast, close to machine language, and supported by advanced libraries. As a result, entire operating systems or critical components of them can be written in C++. A significant portion of macOS is written in C++. Additionally, much of Microsoft’s software—including Windows, Microsoft Office, Visual Studio, and Internet Explorer—is developed using C++.

• Games: Because C++ provides high performance and low-level hardware access, it is the primary language used by game development companies to build game engines and systems. For example, Unreal Engine is largely developed using C++.

• GUI-Based Applications: C++ is not limited to command-line programs. With frameworks such as Qt (Graphical User Interface), developers can create powerful and visually rich graphical applications.

• Web Browsers: One of the most important factors that differentiates web browsers is speed. When performance is critical, C++ is an excellent choice. Large portions of Mozilla Firefox are written in C++, and the core components of the Tor Browser are also implemented using C++.

• Embedded Systems: When software needs to interact closely with hardware, C++ is often the first choice. Smartwatches, medical equipment systems, and many other embedded systems are largely developed using C++.

• Banking Applications: Banking software requires high performance, synchronization, multithreading, and concurrency. For these reasons, C++ is commonly used in the financial sector. Infosys Finacle is a well-known banking application developed using C++.

• Compilers: Many programming language compilers are written in C++. This is because C++ is a low-to-medium-level programming language that provides close interaction with hardware while still supporting high-level abstractions.

• Cloud/Distributed Systems: High-performance cloud and distributed systems often need to operate close to the hardware. This makes C++ a strong choice for implementing such systems. Its robust multithreading capabilities also enable the development of highly concurrent and fault-tolerant applications. Bloomberg’s core systems are written in C, while its development environment and libraries are implemented in C++.

• Libraries: Software libraries often require intensive mathematical computations, high performance, and speed. As a result, many widely used libraries are written in C++. One of the most popular machine learning libraries, TensorFlow, uses C++ as its backend programming language.

  
  

Conclusion

In conclusion, if you want to elevate your programming skills and take an active role in a wide range of software development fields, C++ is an excellent choice. It provides the performance, flexibility, and control needed to work across nearly every area of the programming industry.
