Take any binary (written in C) and do a ldd binary, and take a look at what language they are written, and you obviously know that they DO use other libraries.

Take any binary (written in C) and do a ldd binary, and take a look at what language they are written, and you obviously know that they DO use other libraries. The difference is that C people usually has a different view on the data structures, in a sense that under system level programming context most of the data structures will be much more efficient when adapted into the context. That's why you did not see that many "universal" C data structure library because they know it is a hard thing to mess up with if you need efficiency.
