Yes.  All of those symbols are part of the standard C++ library.. none of 
those exist in the standard C library.  When you invoke the gnu compiler 
suite using 'gcc', it assumes (regardless of what you call your file) that 
the file is a C file.  Since it is C++, you'll need to invoke it with 'g++'

So this will work:

g++ main.cpp
