OK, it was not at the top - Java is still King - but was a number two above Python – which is a little surprising.
C is considered the red-headed stepchild of programming these days and most people consider Python emerged as the most productive and popular language in recent times and, apparently, the language had a good year due to the Internet of Things.
C is really good with small devices that are performance-critical with limited resources. It is a feature-rich programming language, including direct access to machine level hardware APIs. There are lots of C compilers, deterministic resource use and dynamic memory allocation.
If you want to write a decent driver or embedded system or control micro-controllers and use various functionalities C suddenly becomes really useful.
C can be used for scripting system applications for every operating system like Windows, UNIX, and Linux.
