File does not output when adding the date to it

I would like to output an error report for my code with a filename formatted as "ErrorReport_date_time.rpt". as of right now i can output a file as "ErrorReport.rpt" or with no extension but when adding the date and time, it does not create a file.

void ErrorHandler::Open(char const filename[])
{
    string fileType = ".rpt";

    time_t t = time(0);
    struct tm * now = localtime(&t);

    stringstream ss;

    ss << filename
       << (now->tm_year + 1900) << '-'
       << (now->tm_mon + 1) << '-'
       << (now->tm_mday) << '_'
       << (now->tm_hour) << ':'
       << (now->tm_min) << ':'
       << now->tm_sec
       << fileType
       << endl;

    fileHandler->OpenFile(ss.str());
}

Supposing that my file handler opens, closes, and writes to a file successfully, where would I be going wrong?

Solution

  • You can't use : or endl in file names.
