Basic While Loops - count up the elephants

If you enter a number, you will receive that number of alerts counting up to that number of elephants.

If you don't enter a number, the prompt will continue to ask you for a number.

Script could be improved by adding a small if statement into the second while loop (the one that counts up) to adjust the alert string according to whether or not c is 1 (singular elephant) or greater than one (plural elephants)
