How do you delete a record from a file in c plus plus?
Deleting a record from a file requires that the entire file be re-written to a temporary file, skipping over the deleted record. Once complete, delete the original file then rename the temporary file with the original file name. Whilst this is trivial for small files with relatively few records, it is unworkable for much larger files which could take many minutes to rewrite. So rather then delete a record, simply mark the record for deletion instead. This can be done by using a field within the record itself (or a single bit within a bit field). As well as improving efficiency, it also provides the option of restoring records at a later date (akin to a recycle bin). To permanently delete the marked records -- known as a purge -- simply rewrite the entire file, skipping over the marked records, just as you would for a single record.
