Instructions

Write a program which must:

• Allocate (with make) an array 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 array.

Errors should be handled.

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