 ### Instructions
 
-Write a program which must:
-
-- **Allocate (with `make`)** a slice of integers.
-
-- Fill it with consecutive values that begins at the first argument and end at the second argument (Including the values of thoses arguments !).
-
-- That prints the slice.
+Write a program that takes two numbers as arguments and prints the consecutive values that begins at the first number and end at the second number (including the values of those numbers !).
 
 Errors should be handled.
