please get the netpbm library (netpbm.sourceforge.net) which provides the functionality to load/store images in .pgm/.ppm format and
also features a
getopt() implementation

MSVC probably has some compatibility functions for srandom()/random() (maybe called _srandom() or rand48()) -- if not you can try to
use rand() / srand() instead
