C is a good language, but as to whether it's been around for years or not, it really doesn't depend on the language as much as the compiler that you're using. There's a lot that don't fully support ISO C99 or C11 for instance, especially if you're on Windows. C may have been around for a while but it's evolved over the years too, just not as much as C++, but big companies like Microsoft have put much more effort into working with support for C++ rather than C. C is still a good language though, but don't expect to be writing code using all of the new C11 features with flawless results 100% of the time.

Personally, my development environment is a terminal, nano, and gcc.

You sort of indirectly replied to my post to hint at the fact that you're on Linux.
