I'm working with a project for my data structures class and i need to create blank files to send information to and they need to be given a name entered by the user of the program.

Example:
   The user is going to enter information on a town named Charleston.  How do i create a file with the name Charleston once the user enters the name of the town.

I already made the class that sends the data to an external file but only if the name of the output file is given by me in the code.

#include <fstream.h>

you have a char* filename that contains
the filename that the user entered.

ofstream out;
out.open(filename); //create and open
                    //file for writing
out.close(); //close the file

Good Luck!

you use standard insertion operators like this


int data=564;

out.open(filename);

out<<data;

out.close();

a text file with the name stored in filename will be create which will look like this

564

the insertion operator is used the same way as it is for cout
