A Comparative Study of the Significance of Different Programming Languages
<p>Yi He</p> · Academic Journal of Computing & Information Science · 2025
This paper delves into the characteristics, application scenarios, and efficiency differences of four mainstream programming languages: C, C++, C#, and Java, aiming to establish a solid theoretical foundation for language selection in software development. In terms of efficiency and execution time, C excels in speed due to its close-to-the-metal nature, while C++ demonstrates outstanding overall efficiency. Java matches C++ in efficiency for small tasks, benefiting from its automatic memory management, which reduces development complexity. At the syntactic level, each language possesses distinct features: C is structured around functions; C++ introduces classes and objects, enriching programming paradigms; Java achieves cross-platform compatibility through a virtual machine and incorporates a garbage collection mechanism. These characteristics determine their precise positioning in practical applications: C dominates low-level and system-level development; Java is widely used in enterprise and mobile domains; C++ showcases its strength in various fields such as gaming, office software, databases, and browser development. Through a comprehensive analysis and comparison of these four programming languages, this study not only deepens the understanding of programming language characteristics and application scenarios but also provides a scientific and comprehensive reference for language selection in the software development process.
