The n00b is back...help with outpout to file...

[HardHackz]

Hey, I'm having a little problem editing a file. Whenever I put
something into it, it erases the old thing, is there a way to fix this
so it doesn't erase the last thing?

Learn how to use your editor?

Sorry for double post, but does anyone have any good C++ tutorials
besides the one at cplusplus.com?

No, like this:

// basic file operations
#include <iostream>
#include <fstream>
using namespace std;

int main () {
ofstream myfile;
myfile.open ("example.txt");
myfile << "Writing this to a file.\n";
myfile.close();
return 0;
}

*Please trim signatures*

No, like this:

// basic file operations
#include <iostream>
#include <fstream>
using namespace std;

int main () {
ofstream myfile;
myfile.open ("example.txt");

Look up the use of the second parameter of open, the mode flag. It
defaults to truncating the file.

Next time, *Please trim the signature* that's the bit after the "-- ".
If you use a news reader, it should do this by default.

hey you might have given this thing:
fopen("somefile name","w");
instead of w write "a" which means appending
in this way you wont lose the previous data...

He's using Google Groups, and that's not one of their features.

Google Groups isn't a real newsreader

People got bent out of shape last time I said that, so I refrained from
commentary.

Well, I added a winking smiley, so that should make it clearer that I
was kidding... but not really

this is pertinent. I only could get back to usenet because of
googlegroups. I am sure there is a similar case for many good people
from here

many news servers disappeared or become paid

google sucks, but works (mostly)
