This month’s Tiobe Index of the most popular programming languages looks a lot like last month’s list with two notable changes. First, C extended its lead over Java. Last month, C had 16.975 percent of search engine hits while Java had 16.154 percent. This month, C increased to 17.246 percent, and Java fell slightly to 16.107 percent.
“The reason why C is building up a lead is that C is used everywhere in the programming world, especially in small devices,” said Tiobe’s Paul Jansen. “And the number of small devices is still growing. Even my toothbrush contains software nowadays, and it is probably implemented in C. So the rankings of C will remain stable for many years.”
The other noteworthy change is that Groovy made the top twenty for the first time. Last month, it ranked 22nd, but this month it was 18th.
