Have you ever wanted to predict the future? Well the Magic Eight Ball does just that. The original game was a softball sized 8-ball. You would ask a question, shake it up and look at the result. There are 20 responses10 positive, 5 negative, and 5 are vague. These responses are given in the file responses.txt and listed in the last page. For this project, we want to recreate this, but give the ability to read in a set of responses, and add additional responses, and print out all of the responses in alphabetical order. Of course, we have to give seemingly accurate responses, which we will do by giving a random response. Program Details: You should have a menu with five lettered options. You should accept both capital and lower case letters in your menu options. The menu should do the task, then return to the menu (except in the case of exit). Any incorrect responses should get an error message, followed by a reprint of the menu. a. Read responses from a file b. Play Magic Eight Ball c. Print out responses and categories alphabetically d. Write responses to a file e. Exit Each menu item must be implemented using a function or sets of functions with appropriate input parameters and return values. Functions will have prototypes in a file called functions.h and defined in a file called functions.cpp. Also, you will have a struct for the response and whether it is positive, negative, or vague. That struct will also be in the functions.h file.

Here is a general explanation of what each option should do: a. Read responses from a file: This will read the responses and their category from the file responses.txt into an array. b. Play Magic Eight ball: User will ask a question, and a random response with a category is given from the array. c. Print out responses and categories alphabetically: Need to sort the responses in the array and print them. d. Write responses to a file: Write the array of responses with the categories (on separate lines) to a new file. You can name that file responsesOutput.txt.

Implementation Detail 1: Remember you will need to #include functions.h into both your main.cpp and functions.cpp. Implementation Detail 2: You should have a duplicate guard in your functions.h like: #ifndef FUNCTIONS_H #define FUNCTIONS_H //your code here #endif Implementation Detail 3: In most IDEs, you need to make sure all of your files are included in the project. For VS and csegrid, make sure all files are in the same directory. For XCode, you will need to place them in the same directory, then go to Product->Scheme->Edit Scheme and Use custom working directory where your .cpp and .txt files are located. For the csegrid run your program with g++ -o pa2.o main.cpp functions.cpp. Then run with ./pa2.o

Implementation Detail 4: You must use (at least) one array, and struct. You may not use vectors or classes. Example: struct Magic { string response; string category; }

Implementation Detail 5: You can not have any global variables. So you will need to declare variables in main, then pass them (as appropriate) to your functions. Remember that there is no built in size for arrays, so you will have to pass the size (and MAXSIZE when trying to add to an array) Implementation Detail 6: You will need to choose a random response. See the example at http://www.cplusplus.com/reference/cstdlib/rand/ Note: You need some additional #include statements. You will use srand ONLY once, then use rand() with the modulus operator (%) to get a number between 0 and size -1

It is certain positive It is decidedly so positive Without a doubt positive Yes definitely positive You may rely on it positive As I see it, yes positive Most likely positive Outlook good positive Yes positive Signs point to yes positive Reply hazy try again vague Ask again later vague Better not tell you now vague Cannot predict now vague Concentrate and ask again vague Don't count on it negative My reply is no negative My sources say no negative Outlook not so good negative Very doubtful negative
