That would do it for you alright.  Keep in mind, GCC is an acronym for
'GNU Compiler Collection', of which gcc and g++ are both a part.  A
small thing that seems to trip some people up. If they tell you to
compile C++ code with gcc followed by flags (ie, gcc -o test1 test.cpp)
then I'd start to question the materials' validity ;-)

Off-topic?  You had a problem, you asked, we helped...seems pretty much
on topic to me :)  Hope your future experiences with C++ aren't so
frustrating
