Hmm… I’m wondering if you can make the program so that the user can write to the file? Like, something with cin. Is it possible? It probably is, and has an easy explanation, but I just want to know if it is possible, and how to write the program to do this if it is possible. Thanks!!

Ignore my previous comment, I had overlooked the explanation below (use double backslashes):
“c:\\test\\abc.txt”

This worked for me.

I tried adding the complete path and filename, but it still outputs the file in the projects folder.
Is there a way to actually output the file where you want? It can’t be that difficult…
Thanx

if you given complete file path using single slash separator like “c:\test\abc.txt” try with double slash separator like “c:\\test\\abc.txt”

I do read all the comments (eventually). I don’t know why it wouldn’t be outputting a file. Perhaps you don’t have permission to create files in the output directory? Seems unlikely though. You might do a google search on ofstream() and see if you can find reasons that it might fail. I can’t think of any other obvious reasons.

I believe instead of specifying just a filename, you can specify a path and a filename. I’m not sure which directory corresponds to the windows desktop, but there is one somewhere on your hard drive…

I don’t know if anybody checks these for comments, but outputting to text files doesn’t work for me in Visual C++ 2008 :(

I’ve copy-pasted your output example exactly. The program compiles & runs, but no text file results. What’s happening?

Very nice… I can do a lot with this stuff. :)
By the way Alex :
Is there any way to change where to save the files that we make with ofstream? for example- I want to save my Sample.dat to desktop.
Thanks
