Objective

Build a tiny getopt-style flag parser that walks argv left to right and announces each recognised short option as soon as it appears.

Steps

• The program understands three short flags: -l, -c, and -p. The -p flag is followed by a separate argv entry used as its value.
• For every -l encountered, print exactly Option l\n. For every -c, print Option c\n. For every -p value, print Option p with arg value\n where value is the following argv entry verbatim.
• Each argv token is inspected on its own; combined short flags such as -lc are not supported. Tokens that look like flags but are not -l, -c, or -p are silently ignored.
• Stop scanning as soon as you reach a token that does not begin with -, or as soon as you reach the literal --. Everything after that is treated as a positional argument and produces no output.
• If no extra arguments are supplied, the program prints nothing and exits cleanly.
• Use only the write system call for output.
