## reverserange

### Instructions

Write a program which must:

-   **Allocate (with `make`)** an array of integers.

-   Fill it with consecutive values that begins at the second argument and end at the first argument (Including the values of thoses arguments !).

-   That prints the array.

Errors should be handled.

If the number of arguments is different from 2 the program prints a newline ("`\n`").
