Why don't you give the average American a copy of your C code and ask them if it's in English or not, they'll look at you with a dull eyed stare and probably say something like "I recognize a few of the words, but this is a language?"
Recognizable language in programming is minimal at best, programmers don't think of it that way though because they know how to deal with the native tongue so to speak. Some object oriented languages are more intuitive to the less technically apt that 'pure code' however the point still stands; C is a language in and of itself, the typical 'names' associated with common C functions would make no more sense to a common English speaking non technical native as it would to the Chinese.
