Thread: Save system...

Ok, This is driving me nuts, and searching google just leads me to dead ends so last resort to ask. I am try to create a file save system, but where the user can specify the name of the file. is this possible using ofstream? this wont work but an example of what I am trying to do

Code:

#include <iostream>
#include <fstream>

using namespace std;

int main() {
	 string save = "data";
	 ofstream out ( + data +".txt" );
	 cin.get();
}

So is there a way to do something like that?
Thank you SO much
