自2003年达到峰值后，C++经历了多年下滑，但最新数据显示，C++已成为增长最快的编程语言，涨幅达1.48%，超越R和C#。这可能归因于即将推出的C++20标准及其模块特性，该特性将替代原有的include机制。

September Headline: Programming Language C++ is doing very well

Back in 2003, the programming language C++ was a real winner. It peaked at 17.53% in August 2003, being close to the number #2 position and becoming winner of the programming language award of 2003. From then on C++ went downhill. After 2005 it didn't hit the 10% any more and in 2017 it scored an all time low of 4.55%. But if compared to last year, C++ is now the fastest growing language of the pack (+1.48%). I think that the new C++20 standard might be one of the main causes for this. Especially because of the new modules feature that is going to replace the dreadful include mechanism. C++ beats other languages with a positive trend such as R (+1.33%) and C# (+1.18%). On the other hand, Java is in real trouble with a loss of -3.18% in comparison to last year. - Paul Jansen, CEO TIOBE Software

The TIOBE Programming Community index is an indicator of the popularity of programming languages. The index is updated once a month. The ratings are based on the number of skilled engineers world-wide, courses and third party vendors. Popular search engines such as Google, Bing, Yahoo!, Wikipedia, Amazon, YouTube and Baidu are used to calculate the ratings. It is important to note that the TIOBE index is not about the best programming language or the language in which most lines of code have been written.

The index can be used to check whether your programming skills are still up to date or to make a strategic decision about what programming language should be adopted when starting to build a new software system. The definition of the TIOBE index can be found here.
