i have a question about using C++ to read in data from files which are
not white-space delineated (in fact, some of the data will be in Fortran's
scientific notation (-1.456e+2, for example, and some of the data may
come from dialog boxes).  we are unsure at this point as to how to read
this data in.  cin won't work, and while we have gotten hold of some
sample programs that utilize the "atoi" command, it's only in the context
of the argc and argv commands, and i think those are only needed if we
run this on UNIX (which we're not).  can someone supply me with some info
on atoi, as well as any info about reading in string data?  i may not be
explaining this too clearly, as i'm part of a research group that's just
now learning c++.  we haven't found too much in the documentation that we
have.....

any info would be appreciated
