Always when i search for C i get tons of posts on forums, videos, blogs where people use C in the title - but they actually mean C++ in almost all cases. This is really annoying if you really want to search for specific things made in C only. Sure i could search C89 or C99 but there are much less results for that than "C", but then i would skip the rare "C" only posts...
It would be so much nicer if people would use the proper namings like: C++, Cpp, or C or Ansi-C or C89 or C99... but thats just my thinking.
