Thread: Whats wrong with my program?

The program's purpose is for the user to create a new file name along with the file extension.

Code:

#include <iostream>
#include <fstream.h>
#include <string>

void Stream(char &file, char &ext, ofstream &create)
{
 cout << "Type in a filename: ";
  cin >> file;
 cout << "\nType the file extension(ie: txt): ";
  cin >> ext;
 const char *filename=file + "." + ext;
 create.open(filename);
 create.close();
}

int main(int argc, char *argv[])
{
 char boob, lama;
 ofstream x;
 Stream(boob, lama, x);
 cout << "\nFile created was: " << boob << "." << lama << endl;

 cin.get();
 return 0;
}
