+For this problem, you will write the function
+
+  void reverse(char * str) 
+
+in the provided reverse.c file.  This function should reverse the string
+passed into it (that is, if given "abc", it should change the contents
+of that string to read "cba"). Note that this function's return type
+is "void"---it modifies the string passed into it in place.
+
+We have provided a main function which you can use to test your
+reverse function (do you recognize the quotations?).  The correct
+output for your program can be found in reverse_ans.txt, so you can
+diff your program's output against it.
+
+Submit your reverse.c file for grading.
