In this game, a player is asked by computer to type in several animal names such as "dog," "cat," etc., in the beginning of the game session. There is no limit to the count of the names but these names must be space delimited. When entering a return key without typing anything (i.e., empty line), this process of input cycle ends. So, use getline()discussed in recent lecture to realize this input logic. Then you should break up the line of input being isolating "words".   A word can be defined as a sequence of consecutive non-white-space characters with white space before and after.

Do not use anything from stringstream.  For this assignment you should use functionality from <vector>  and <string> including getline(istream&, string&) and from <algorithm> rand_shuffle function.

The computer will pick up 1 to 3 names from those entered by the player. They are shuffled to produce a random word. The player will be asked to identify the names, given a hint of how many animals in that word. The player needs to type in names (or a name if asked one). Typing "?" will show the name list, and typing "quit" will end the game.

When succeeding to answer in two consecutive rounds, the computer's challenge becomes harder by striking out a character one by one. The position to strike out is chosen at random. So, succeeding 4 consecutive times, the random word has two strikes out shown by underscore "_" characters. On the other hand, failing to answer in two consecutive rounds, the computer's challenge becomes easier by reducing the count of strikes out. The sample session follows.

Enter at least five animal names, e.g., cat, dog, etc...

This assignment will ask you to use <string>,  string::getline(), <vector> and random_shuffle() or shuffle()  from <algorithm>  to  reduce the amount of coding. You can find many examples on the Web -- see here for instance.
