open file

[reddog]

hello im new to c++
normally i would open a file for appending
with a code that looks like

outfile = fopen("test.txt""a");
but now i want to use a variable file name like

string_str()
in place of "test.txt

can anyone please advise a piece of code that might help

Well that's the C way of doing things.

To open a file in C++ for append with a variable path would be

string path = "some_file.txt";
ofstream outFile( path.c_str(), ios_base::app );

Of course include the proper headers

#include <fstream>
#include <string> 

If you get stuck you can always read the documentation on this site.
