### Instructions
|
||
|
|
|
||
|
|
Write a **program** that can have as arguments `--insert` (or `-i`), `--order` (or `-o`) and a `string`.
|
||
|
|
|
||
|
|
This program should :
|
||
|
|
|
||
|
|
- Insert the string given to the `--insert` (or `-i`), in the `string` argument, if given.
|
||
|
|
- Order the `string` argument if given the flag `--order` (or `-o`).
|
||
|
|
- In case there are no arguments or the flag `--help` (or `-h`) is given, it should print the options, as shown in the example.
|
||
|
|
|
||
|
|
Example of output :
|
||
|
|
|
||
|
|
```console
|
||
|
|
student@ubuntu:~/piscine-go/flags$ go build
|
||
|
|
student@ubuntu:~/piscine-go/flags$ ./flags --insert=4321 --order asdad

||
|
|
student@ubuntu:~/piscine-go/flags$ ./flags --insert=4321 asdad
|
||
|
|
asdad4321
|
||
|
|
student@ubuntu:~/piscine-go/flags$ ./flags asdad
|
||
|
|
asdad
|
||
|
|
student@ubuntu:~/piscine-go/flags$ ./flags --order 43a21

student@ubuntu:~/piscine-go/flags$ ./flags
|
||
|
|
--insert
|
||
|
|
-i
|
||
|
|
This flag inserts the string into the string passed as argument.
|
||
|
|
--order
|
||
|
|
-o
|
||
|
|
This flag will behave like a boolean, if its called it will order the argument.
|
||
|
|
student@ubuntu:~/piscine-go/flags$
|
||
|
|
student@ubuntu:~/piscine-go/flags$ ./flags -h
|
||
|
|
--insert
|
||
|
|
-i
|
||
|
|
This flag inserts the string into the string passed as argument.
|
||
|
|
--order
|
||
|
|
-o
|
||
|
|
This flag will behave like a boolean, if its called it will order the argument.
|
||
|
|
student@ubuntu:~/piscine-go/flags$
|
||
|
|
student@ubuntu:~/piscine-go/flags$ ./flags --help
|
||
|
|
--insert
|
||
|
|
-i
|
||
|
|
This flag inserts the string into the string passed as argument.
|
||
|
|
--order
|
||
|
|
-o
|
||
|
|
This flag will behave like a boolean, if its called it will order the argument.
