a.out is an executable. Typing `./a.out' will execute it.
To specify a filename, use `-o', e.g. `g++ source.cc -o myprog'.

To compile a program using make, you generally need a Makefile.
It's possible to do without one if your program consists of a single
file, e.g. `make -k source' will look for a file called
source.<something> and then use the default rule for the extension.
For a .cc file, it would use `g++ source.cc -o source'. More
precisely, it would use
$(CXX) -o source $(CPPFLAGS) $(CXXFLAGS) source.cc
where CXX defaults to `g++', and CPPFLAGS and CXXFLAGS default to
nothing.
For more details, see the `make' info file (`C-h C-i make').
