The C family of languages is incredibly popular if you go by the TIOBE Programming Community Index. That has not changed going into June 2013, but one language is creeping up fast.
In other news, Objective-C is climbing its way back up the Community Index. In April, growth had stalled and it slipped behind C++ to rank 4. Now it's back on top of C++. It's most likely due to an increase in iOS development. It will likely only increase in the coming months as well with iOS 7 on the horizon.
The only other change among the C family is that C# has fallen to sixth place after being dethroned by PHP. It's only a regular fluctuation though, and I wouldn't be surprised to see it back up next month.
