# options

## Instructions
|
||
|
|
||
|
Write a program that takes an undefined number of arguments which could be considered as options and writes on the 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
|
||
|
- ******zy xwvutsrq ponmlkji hgfedcba
|
||
|
|
||
|
- Launching the program without arguments or with the `-h` flag activated must print all the valid options on the standard output, as shown on one of the following examples.
|
||
|
|
||
|
- A wrong option must print "Invalid Option" followed by a newline.
|
||
|
|
||
|
