To find the approximate place where this entry was judged, type:	whereami 37 -122	(- means west of meridian)    Selected notes from the author:    Run the program with your latitude & longitude as integer    arguments; it will produce a map made up of '!' with the given    position marked with either a '"' (if the position is over a '!')    or a '#' (if the position is over a space).  Southern latitudes    and western longitudes are entered as negative numbers.  For    example, to find San Francisco, run with "prog 38 -122".  The    resolution of the map is five degrees horizontally, ten degrees    vertically.  The map is a Mercator projection with equal spacing    of the latitudes, so the areas near the poles are very distorted.    Latitudes near the poles and Antarctica are not shown.    The program requires the ASCII character set, putchar(), atoi(),    and a display that auto-wraps at 80 characters(!).  If your display    does not work this way, you will have to massage the output;    for example, you can pipe it to a file and edit it with vi,    which will do autowrap for you.    Lint complains that main() returns a random value and I'm not    checking the value that putchar() returns.  Scandalous!    If you run it with fewer than 2 arguments, it will likely    give you an exception, as it will access arguments that    don't exist and characters before a string constant.    How it works:    The map is printed as one long string of ' ' and '!' characters,    with the autowrap used to stack up slices of 80.  The map data is    a string; the first character is how many '!'s are printed    ('A'=1, 'B'=2, etc), the second character is how many ' 's, the    third is how many '!'s, etc.  ASCII characters less than 'A'    print no characters but still change the polarity, so any map    of ' 's and '!'s is possible.  This is done in the putchar()    argument as "33^l&1", where l is the character position+4; if    l is odd, ' ' is printed, if l is even, '!' is printed.    The position of latitude & longitude is changed into a single    character position within the one long string via the first    expression "d = latitude/10*80 - longitude/5 - offset"  The    latitude is divided by ten because the vertical resolution is    ten degrees, then multiplied by 80 because of the 80 character    wrap (i.e. each ten degrees moves the position up or down one    entire row).  The longitude is divided by five and added, because    five degrees of change moves the location one character.  The signs    are opposite because latitude is decreasing and longitude is    increasing as you go from upper left to lower right.  The offset    is where the origin (latitude=0, longitude=0) is found.    The position counting down to zero changes the putchar() from    printing ('!' or ' ') to printing ('"' or '#').    The "H E L L O,   W O R L D!" string inside the data string    prints the line of blanks past Tierra del Fuego and the last    blank line.  It's just for show, really.    Since the resolution is coarse, a few costal cities are shown to    be just off the map; this is an unavoidable artifact.  The map    is reasonably accurate.    Here are some cities you might like to try:         New York  41  -74       Los Angeles  34 -118           London  52    0             Paris  45    2           Moscow  56   38           Beijing  40  116        New Delhi  29   77    Rio de Janeiro -23  -43           Sydney -34  151             Tokyo  36  140For a domestic (USA) version with higher resolution, try:---cut---main(l,a,n,d)char**a;{for(d=atoi(a[1])/2*80-atoi(a[2])-2043;n="bnaBCOCXdBBHGYdAP[A M E R I C A].AqandkmavX|ELC}BOCd"[l++-3];)for(;n-->64;)putchar(!d+++33^l&1);}---cut---The code will test the 80-column wrap and document itself if it isjoined together as one 160-character line and listed.  You should see:main(l,a,n,d)...[A M E R I C A]......going down the left edge if your terminal autowraps at 80 characters.
