I'm having some trouble implementing a basic calculator using command line options. The script is supposed to take (multiple) arguments -a,-d,-m,-s for addition, multiplication, division, and subtraction. I'm pretty sure I know how to parse through the options with getopt(), but I have no idea how to get both arguments to operate on (ex: 7 -a 7, no idea how to get both 7's). I'm pretty sure I can get the first one, but no idea how to get the second.
