Umm, if you open the file for *read*, you can't write to it. You want
"open file x" or "open file x for update" (both of which opens it for
both read *and* write) or "open file x for write" or "open file x for
append". Also note that after reading from the file until eof, the
file pointer is at the end of the file, meaning all writes will extend
the file rather than overwriting the data in the file.
Finally, you should check the result after opening a file: if there
was an error (bad file name, or no permission to open the file for
that mode), it'll tell you.
