2025 年 10 月编程语言排行榜｜C、C++、Java 第二名之争愈演愈烈，Python 继续称王

Core Insights - The TIOBE index for October 2025 highlights the fierce competition for the second place among programming languages, with Python maintaining its first position since late 2023 [1][2]. Ranking Dynamics - C, C++, and Java have been in a tight race for the second position, with their ranking differences consistently under 1% over the past year [4]. - C has reclaimed the second position, while Java has consistently followed closely behind [4][5]. Language Advantages - The resurgence of C to the second position is attributed to the release and application of the C23 standard [5]. - C is recognized for its speed and efficiency as a foundational language, C++ is essential for large systems and embedded development, and Java dominates in enterprise-level and backend applications [7]. Trends and Observations - The overall trend for C, C++, and Java has been a gradual decline, with Python gaining popularity in various fields such as AI, data analysis, and automation [9][11]. - Python's dominance is evident, holding a significant lead with a rating of 24.45% [12][13]. Emerging Competitors - C is rapidly closing the gap with C, C++, and Java, reducing the difference from 4% at the beginning of the year to just 1.4% [14][15]. - The growth of C is attributed to the continued development of the Microsoft ecosystem and the maturity of the .NET platform [15]. Historical Context - The TIOBE index reflects the popularity and usage trends of programming languages rather than their strength, indicating a shift in developer focus due to new demands and technologies [19][20]. - C and C++ remain irreplaceable in operating systems, drivers, and game engines, while Java continues to be a stable choice in finance and enterprise systems [21][22]. Conclusion - Continuous learning and adaptation are essential for programmers, as no language is immune to obsolescence, only the programmers can become outdated [23].
