find_last_e

Your mission

Write a program that scans a string and prints the last lowercase e it finds.

See it in action

./find_last_e "merge later, test first"

Expected result

Your checklist

For your own tracking. Tests grade your code.

Expect exactly one user-supplied argument (argc must be 2).
If argc is not 2, print e followed by a newline.
Otherwise, scan the entire argument and locate the last occurrence of the lowercase letter e.
Print that character followed by a newline.
If the string contains no lowercase e, print only a newline.
