C++ Encourages a Deeper Understanding of Computer Science

Behind every robust software application lies a foundation of core computer science principles. Take, for example, the Git version control system, which employs graph theory, hashing, and various essential algorithms. The following shows a merge sort implementation from the Git codebase:

In today's tech landscape, businesses are increasingly shifting towards cloud computing and automating processes. As a result, many programmers find themselves focused on resolving business-related challenges rather than strictly computer science issues.

Nevertheless, even when working on business-centric projects, applying theoretical computer science knowledge is vital for writing high-quality, efficient code. Consequently, a solid understanding of computer science is indispensable for every programmer.

While C++ is a high-level language that offers more human-friendly abstraction than C, it also encourages the use of pointers and manual memory management—concepts that are more technical and foundational. The C++ standard library prioritizes performance and flexibility, rather than just ease of development. Therefore, learning C++ naturally leads to a deeper grasp of computer science fundamentals.

Creating Efficient, Lightweight Solutions with C++

Many contemporary programming languages emphasize obscuring technical details with simplified syntax, often neglecting performance, efficiency, and flexibility. In contrast, C++ excels in producing lightweight binaries, making it ideal for performance-oriented software development.

Languages like Go attempt to rival C++ with their minimalistic syntax and automatic memory management. However, Go tends to generate larger binaries, making it less suitable for scenarios where size matters. Thus, while Go is often employed for high-performance cloud tools, many developers still prefer C++ for lightweight software projects.

For instance, when importing the fmt package, Go’s binary size can increase from 1.2 MB to 1.8 MB, whereas including iostream in C++ typically raises the binary size from 16.5 KB to 17.3 KB. This demonstrates that C++ retains a more efficient size increase, proving it to be superior for high-performance and compact software solutions.

While C++ is complex and feature-rich, it allows developers to select specific features to maintain minimal code. The following resource discusses programming principles that can enhance coding quality:

Learning Other Languages Becomes Easier with C++ Proficiency

Programmers often pick languages based on personal preference. Some learn programming languages when transitioning to enterprise-level projects, while others pursue them as a hobby. While some languages are relatively easy to pick up, others demand ongoing experimentation for mastery.

C++, with its intricate syntax (consisting of 60 keywords), comprehensive standard library, and hardware-centric development environment, requires more time to achieve proficiency. It is a multi-paradigm language that allows for personalized coding styles and best practices.

Gaining familiarity with the C++ standard library and its development patterns necessitates a solid foundation in computer science. Thus, once you become proficient in C++, picking up new languages becomes significantly easier.

C++: The Best Language for Interfacing with Operating System APIs

Every operating system provides a programmable interface for developers to manage processes, handle files, render GUIs, and manage network requests. These APIs predominantly utilize C/C++-based interfaces, as most operating systems are built using these languages.

For instance, GNU/Linux systems offer Unix-like APIs and GTK GUI libraries in C header files, while Windows provides its well-known Win32 API functions. macOS also offers Objective-C interfaces compatible with the Apple Clang LLVM compiler. Consequently, C++ developers can access operating system-level APIs directly, given that C++ is a superset of C, and Apple compilers allow for a mix of C++ and Objective-C. Here’s an example of how Electron utilizes GTK C headers from C++ source files:

Other programming languages typically require language-specific bindings to access these operating system APIs. This is why many operating system-level frameworks are developed in C++. Notable C++-based frameworks include:

• Electron
• React Native
• Flutter
• Neutralinojs

Additionally, major software projects like Chromium, Firefox, TensorFlow, LLVM, and V8 predominantly utilize C++.

C++ Knowledge Enhances Technical Decision-Making

Programmers do more than just write code; they also design software systems and structure projects effectively. The design phase is critical, as it lays the groundwork for the entire software project. Throughout this phase, programmers often face technical decisions that influence both design and development.

C++ is a multifaceted language that offers numerous solutions to the same programming challenges. It is inherently fast, allowing programmers to optimize code as desired. Thus, careful consideration is required when selecting C++ features that best suit specific needs.

Although primarily known as an object-oriented programming (OOP) language, C++ supports multiple paradigms, including procedural and functional programming. Some developers even avoid certain C++ features to simplify their code. For instance, the Google C++ style guide recommends against the use of C++ exceptions. Such scenarios foster improved technical decision-making skills.

Conclusion

This article has highlighted the significant advantages of mastering C++ in your programming journey. While there are over twenty established and feature-rich programming languages, there is no definitive "best" language; each excels in particular areas. Therefore, it is wise to select five programming languages that resonate with you and consider them your "best programming languages."

If you make thoughtful choices, C/C++ will likely earn a spot on your list. I elaborated on my favorite programming languages in a separate article:
