Instructions
Write a program that takes an undefined number of arguments which could be considered as options and writes on standard output a representation of those options as groups of bytes followed by a newline.
-
An option is an argument that begins by a '-' and have multiple characters which could be :
- abcdefghijklmnopqrstuvwxyz
-
All options are stocked in a single int and each options represents a bit of that int, and should be stocked like this :
- 00000000 00000000 00000000 00000000

-
A wrong option must print "Invalid Option" followd by a newline.
