    File I/O with a current Date

    I know how to do File I/O and such, but I was wanting to put the time and date on the top of one of my documents that was output. Besides typing it it how would I go about this? I copied some code for how to display the time and such during a program, but since I just copied the code I don't know how it works , and so I don't know how to write it to a file.
    Any help is well appreciated!

    If the code you have got uses the tm data structure to hold the time, then all you have to do is output each member individually to the text file, or convert the time_t variable to a string and output that.

    Post The code I have...

    The code I have, and use, looks like this.

    Code:
    time_t now;
    time(&now);
    printf("Current Time: %.24s.\n", ctime(&now));
    Is this the circumstance you were talking about subdene?

    try this.

    Code:
    #include <time.h>
    #include <fstream.h>
    
    int main(void)
    {
      const char FILE_NAME[]="Test.txt\0";
    
      char *Date;
      fstream File(FILE_NAME, ios::out);
    
      time_t now;
      time(&now);
      Date=ctime(&now);
    
      File << Date;
      File.close();
    
      getchar();
    
      return 0;
    }
