C ++ primer Chinese Version 4th exercise 9.13

/* Here I will write down some of my answers and comments for the exercises in C ++ primer 4th (Note: I didn't buy an answer book, so it is not guaranteed that it is correct. What do you think is wrong, I hope you can tell me) the requirements for source code running are the same as those in the book. The pre-compilation and using lines are omitted. If you still don't know what to say, you can ask me, but I am also a beginner and may not know, I know that I am a beginner when I am still studying C ++ Prime. You are welcome to repost it, but please keep the author's name "jiutian Yuling ". */
