Get specific line from text file

I am trying to get a specific line in a text file which only has one word per line and copy it to a string. Can anyone give a simple example?

thanks

You cannot "get" it directly from a file.
You should read the whole file line-by-line and only save the lines you do need.

thanks I figured that one out, how about writing a word to the line you want.

Is it possible to post an example please?

thanks

The same way: read the file, change the line you want to, then write in to the file back (overwriting it)

This is what I used to read a specific line. :

Code:

---

ifstream f("input.txt");
        string s;
        getline(f, s);
        getline(f, s);
        getline(f, s); //here is 3rd line
       
        f.close();
       
        cout << s << endl;

---

I need to overwrite that line now, can you post some hints pls.

thanks

You cannot overwrite "one line only". You have to overwrite the whole tail of the file beginning with this line.

Where can I find more examples using the fstream and familiarize myself with it?

thanks

1. MSDN
2. Google
3. CG Forums.

Just search for the appropriate examples/samples...
