+// General : the program gets a string and searches for the longest
+//              word in it and saves it.
+//
+// Input : a string and a  pointer of pointers.
+//
+// Process : the program goes over the array and checks if each
+//              word finds is longer than the last one that
+//               was longest.
+//
+// Output : the longest word.
