The venerated C++ language has been Tiobe's biggest climber so far since July 2014, according to a report accompanying the July index. "Compared to last year, C++ gained more than 3.1 percent, leaving Java (plus 2 percent), C# (plus 1.6 percent) and Python (up 1.6 percent) behind," the report states. C++ has a rating of 8.641 percent in July, compared to 5.521 percent a year ago. Tiobe bases language popularity on a formula that assesses searches on languages on sites like Google, Wikipedia, and Bing.
Formalized in 2011, C++ 11 introduced capabilities like standard and type-safe support for thread-level and lock-free concurrency. C++ 14, completed last year, expanded on version 11 while adding the ability to express Lambdas generically, among other improvements. In an interview with InfoWorld last summer, C++ designer Bjarne Stroustrup said the language's sweet spot is its ability to handle complexity while still running fast.
Tiobe Managing Director Paul Jansen sees the recent support for C++ 11 in compilers as helping the language's cause. "This is the moment we see that industrial projects are making the choice to adopt these new C++11 compilers and use the new language features," he said in an email.
Following Java in the RedMonk rankings were PHP and Python, with C#, C++, and Ruby in a three-way tie for fifth place. RedMonk sees Go and Apple's Swift, ranked 18th, as languages to pay attention to going forward. "Between Go's increasing popularity as a modern back end language and Swift's bid for traction outside of the iOS landscape, the next few iterations of this list will be interesting to watch."
