words_back

Words and tokens24

Objective

Write a program that takes a single string argument and prints its words in reverse order.

Steps

Words are separated by spaces or tabs.
Inputs are well-formed: no leading or trailing separators, and no consecutive separators between words.
Output the reversed word sequence separated by single spaces, followed by a newline.
If the program receives anything other than exactly one argument, print wrong number of arguments followed by a newline.
You may use write, malloc, and free.

examples

$ ./words_back "hello world"

world hello

$ ./words_back "one two three four"

four three two one

$ ./words_back
