There are multiple ways of reversing a string but here you have to follow a specific algorithm. First, you have to count the number of words in the string; we assume that words are separate by one space and that no other punctuation exists. Then you have to create a array of strings, each item being one of the words. The last item is NULL to mark the end of the array. If item are ordered from the last word to the first word, recomposing the reserved string only consists in concatenating these words in sequence str "Let There Be Light" words "Lightl0" "Bel0" "There\0" "Let 0 NULL rev "Light Be There Let" Word reverse Write program word_reverse.c that reverse all the words of a line, as illustrated in the following example: $ echo "Let There Be Light" | . /word-reverse Input: Let There Be Light Output: Light Be There Let Here are a list of requirements, assumptions and hints: There are multiple ways of reversing a string but here you have to follow a specific algorithm.
