    Okay,
    This is what I used that works:

    #include <iostream.h>
    #include <stdlib.h>
    #include <fstream.h>
    #include <iostream.h>
    #include <windows.h>
    #include <conio.h>


    int main()
    {


    char str[30];
    cin>>str;
    strcat(str,".txt");
    ofstream a_file(str);
    a_file << "sadfasf";

    return 0;
    }

    Now, what do I do if I want to delete the file?
    Thanks

    a_file.close();

    -Prelude
    My best code is written with the delete key.

    Jesus... that is a lot of includes...


    Code:
    #include <iostream> // for standard i/o
    #include <fstream> // for file i/o
    #include <stdlib> // for system call
    using namespace std;
    
    int main()
    {
    
       ofstream outs;
       char answer = 'n';
    
       outs.open("file.txt");  // open/create file
    
       outs << "This is some text in a file";
    
       outs.close(); //close file
    
       cout << "do you want to delete file (y/n):";
       cin   >> answer;
    
       if ((answer == 'y')||(answer == 'Y'))
           system ("del file.txt"); // delete file
    
       return 0;
    
    } // end main
