    is.open("FileName.bin");   // Open the file
    if(is.good())                    // If file is opened successfully
    {
           // calculate FileSize
           is.seekg(0,ios::end); // move 0 bytes from end
           fileSize = is.tellg();   // get offset
           is.seekg(0,ios::beg); // rewind
     }

      cout<<"File Size is : "<<fileSize<<:" bytes";
}
