Hi,
I've got a problem with opening files to output to. I'm being passed a string, but I've got to use that to open up a file without using a dynamic character array. I can use stringstreams but I don't know how I can convert my string into something that an ofstream.open command will accept as an argument. Any help would be appreciated.

You could use open but I open the file in the ofstream constructor.
Code:#include <iostream>
#include <fstream.h>
using std::string;
int main()
{
string strFilename( "c:\\dang.txt" );
fstream oFile( strFilename.data( ), ios::out, filebuf::sh_write );
if( oFile.is_open( ) )
{
oFile.close( );//could just let the ~fstream destructor close it
}
return 0;
}
why can't you do something simple like declaring an array that should hold any possible input string to accept input then proceed as usual. You may have to add double backslashes if path has backslash(es) in it when written in standard english.
char input[256];
//filename for out put file coming from an input file
ifstream fin("data.txt");
fin >> input;
//now use input as name of output file
ofstream fou(input);
