No it isn't.
When I tried to compile the code you gave I get all these errors:
./fileio.cc: In function `int main()':
./fileio.cc:6: error: `cout' undeclared (first use this function)
./fileio.cc:6: error: (Each undeclared identifier is reported only once for
each function it appears in.)
./fileio.cc:6: error: `endl' undeclared (first use this function)
./fileio.cc:7: error: `ofstream' undeclared (first use this function)
./fileio.cc:7: error: expected `;' before "file"
./fileio.cc:8: error: `file' undeclared (first use this function)
./fileio.cc:8: error: `FILE_NAME' undeclared (first use this function)
./fileio.cc:8: error: `ios' has not been declared
./fileio.cc:8: error: `out' undeclared (first use this function)
... and the moral of the story is "If you want people to help you with a
problem, don't tell them lies". Show them the REAL code, not a useless
snippet that won't compile.

There are known to be bugs in 2.95 and in particular in 2.95's version of
the C++ runtime and STL.
I nearly didn't bother, because I had to go look up which headers to
include and fix your non-compiling code, but I was feeling generous, so I
fixed it and built it with current gcc-3.3.3; it works fine with that.

Well, you need to have a serious think about that, because your
application clearly won't work with that older one either.
cheers,
