wassap.
we'll i'm working on a project right now, and i need to be able to jump to a certain spot in the file, delete the info there, and then resave the file. ex (in file itself, on hard drive):
TOM
JOE
BOB
MARY <----need to jump right to this spot, and delete this name
JANE
HARRY
the only method i know is to read in the entire file, search the entire file, erase that name, then rewrite the file. this is a bit tedious. anyways, any help would be appreicated.
thanks a lot
Every programming textbook includes a chapter on file processing.
It covers sequential and random access processing. If you don't
have a textbook or some other suitable How-To-Program book,
you should get one. Other than that, you can start by researching seekg(), seekp(), tellg(), tellp(), the IOS class
members for open_mode (in, out, ate, app, trunc, ...), write(),
sizeOf(), clear(), ifstream(), ...
hth,
i'll try that. thanks
Could you please give us a concrete example?
