adding text to top

[kippwinger]

Hey, I am trying to add text to the top of a text file via a c++ program. Sound confusing? Okay, my program starts out by asking for input. When done entering the input, it outputs it to a text file. Now, I want to be able to open the text file later on and add some more info. However, I want the new data to be added to the top of the text file already created (not deleting previous data)
Example of text file layout:

new data
old data
old data

if you could point out a good resource for this, that would be most helpful.
thanks,
Ben

1) Read in all the lines from the file (e.g. using an array of strings)
2) Close the file and reopen it, which will erase the file.
3) Read in the input from the user.
4) Write the input to the file
5) Write the array of strings to the file.

hmm. Well, I was hoping I wouldn't have to do that. I was hoping that there would be a simple solution. Like ios::nocreate and some other instruction to keep it at the top. Oh well. Thanks for the help.

yes you can open the file with ios::app
and then move the postion to the beginning fo the file,
with seekg()

I was hoping that there would be a simple solution.

That is a simple solution, and it's easy to code.

Ilovevectors: thanks for the tip.

7stud: It sounds easy enough to code. I just wanted it to be easier in that I didn't want to have to create somthing else for this to work (reading data into array). Thanks for the suggestion though.
