/*
ProgEx21 -- Reason why I'm stuck! (program should run as C or C++)
In ProgEx20 we showed how to write a comma delimited text file. In this
program I write my name out to a text file and attempt to read it back in with
fscanf, which is something of a counterpart to BASIC's Input #fp statement -
but not quite. As you can see in the output below - or in real life if you
run the program, only my first name comes back out of the file! Not good!
You might be able to guess what happened. The fscanf (with files) or scanf
breaks at white space and doesn't give a hoot about commas!
However, fscanf and scanf can be useful. Lets take a short look at scanf and
fscanf before tackling classes. Continued in ProgEx22.
