[Resolved] File Writing Help

I have this function:

Code:

---

void addmovie() {
    char string[50] = {'\0'};

    ofstream outFile("C:\\test.txt", ios::out);
    if (!outFile) {
        cout << "File could not be opened!" << endl;
        exit(0);
    }

    cout << "String: ";
    cin.ignore();
    cin.getline(string, 50, '\n');

    //outFile.seekp(outFile.eof());
    outFile << string;
    outFile << '\n';
}

---

How can I make it output at the end of the file, rather than overwriting it?

I thought about reading the file, and adding to it, then writing it back...but is there any other way?

Instead of ios::out, try ios::app

:)

I would suggest doing this:

Code:

---

string s;
getline(cin, s);

---

It's safer than your 50 character limit.

I would love to, however my teacher will not allow it.

crptcblade, I'll give it a try.

******* *****. I don't care what they think. Limited character arrays in a C++ program have NO PLACE WHATSOEVER. Trust me, I have been bitten on this. If your teacher has a problem, then they can come on here, and argue with those of us that have to put up with the problems caused by the ******* shoddily coded software that ends up being put out these days.


******s. They put their "qualifications" above common sense, and well known effects.

I agree with you, Mike. I really do. But right now all I care about is getting a grade I deserve, and stirring up controversy isn't going to get me that.

Well. You have a choice.

1. A qualification.

2. Knowing that you are actually capable of doing something, and thinking for yourself.


Oh, FYI, I have no qualifications concerning programming whatsoever.


PS: I actually would quite like to speak to your teacher/instructor, if you can get them to PM me on here it would be greatly appreciated :)

And when there are buffer overflow security bugs in an app people complain :rolleyes:

Go whine somewhere else. There's nothing I can do about it.

There is, it just takes guts.

Exactly. Use the string class and tell your teacher to **** off. Or maybe explain to him in reasonable words that there is absolutly no reason not to use the string class and that it has many advantages in many ways.
