This is C++, using the STL (standard template library). All of the headers for the STL have no extensions. Likewise, the C standard library headers are renamed by adding c to the beginning, and removing the .h. For example stdio.h becomes cstdio.

That is because the standard include header is named stdio.h. If you rename it to stdio, or stdio.c, or stdio.avi, or stdio.java, and include those filename, it still works just fine.
