File Manipulation

[Darren]

Hi All,

could anyone PLEASE halp me, i'm very new to c++, but i need to do the
following:

open data file
read file from X to Y
create a new file called X.txt
write data inbetween X and Y into file X.txt

just keep getting stuck at how to creta a file with a name known at runtime.

The names X.txt are call numbers, read from a data file, and the data is a
call log. Just want a way to split up the 1 huge file into individual files
with the name of teh call number.

All suggestiosn VERY welcome.

Many thanks,

Darren

#include <iostream>
#include <string>
#include <fstream>

using namespace std;

int main ()
{
cout << "Enter the name of the output file: ";
string filename;
cin >> filename;

ofstream outfile (filename.c_str());
outfile << "fee fie foe fum" << endl;
outfile.close();

return 0;
}
