Reverse word order: write a program that reverses the order of the words in a given sentence. this program requires reversing the order of the words wherein the first and last words are swapped, followed by swapping the second word with the second to last word, followed by swapping the third word and the third to last words, and so on. your program will ask the user for an input string and print out the resultant string where the order of the words is reversed. see the hints section for more details on an example algorithm. assume a maximum c-string size of 1000 characters.
