+
+
+1. My program will simulate an app that acts as a directory to keep all the user's contacts in place. Unlike a regular contact book, this program would also be able to categorize contacts and add ratings.
+
+Functions of the program:
+- Store contacts
+- Categorize contacts into groups such as family, food, clothes
+- Create categories
+- Add and edit details to each contact, which are name, telephone number, ratings(for businesses especially), category and address
+- Display a list of all the contacts under a category
+- Display chosen contact's details
+
+What the program cannot do:
+- Text and call
+
+2. Detailed Examples of Concept Implementation
+Input
+- takes in contact details from user i.e. name, telephone number, rating, address, category
+- takes in category name from user
+- takes in commands from user such as to display a list of all contacts in a category, display the chosen contact's details, or edit contact details
+
+Output
+- displaying contact details
+- displaying categories
+- displaying contacts under a specific category
+
+Conditional Statements
+- Processes user commands to see what they would like to do, such as create a contact, edit contact details, create new category, etc.
+
+Loops
+- For loops to print out contents of a category
+
+Functions
+- Function to add contact details to a category
+- Function to create new category
+- Function to finish program
+- Function to display category contents
+- Function to display contact details
+
+Arrays/strings
+- Each category would be an array
+- Each contact detail is a string
+
+Advanced data types: structs
+- Each contact would be a struct that would contain name, address, telephone number, rating and category
+
+3. Reasons for picking this project
+I chose to do this project because I wanted to create some kind of 'app' that someone could use on a phone. I also wanted to do something that could be quite useful, compared to games.

+Contact Book
+
+This is a contact book that is able to:
+- create and store contacts
+- add and edit details to each contact
+- organize contacts into custom categories
+- display contact information
+
+To navigate the application, use the number keys to select an option that is displayed.
+All functions and instructions will be displayed on the screen. Enjoy!

-Contact Book
+My Contacts App
 
-This is a contact book that is able to:
-- create and store contacts
-- add and edit details to each contact
-- organize contacts into custom categories
-- display contact information
+July 15, 2016
+Julia Tan
 
-To navigate the application, use the number keys to select an option that is displayed.
-All functions and instructions will be displayed on the screen. Enjoy!
+Overview
+The My Contacts program is designed to be an efficient contacts directory that is simple and user-friendly, yet allows for quick access to contact details. Unlike a regular contact book, this program is able to categorize contacts into groups, and also add ratings, which is especially useful for businesses such as restaurants.
 
-Julia Tan
-July 15, 2016
+Functions
+This contact book is able to:
+- Create and save your contacts
+- Add and edit details to each contact, which are name, telephone number, ratings and address
+- Create categories to store your contacts under
+- Display all your contacts under a category
+- Display all categories
+- Display contact information of a contact
+
+How to Use
+To navigate through the application, use the number keys to select what you want to do. Options of what the application can do for you at the current time will be displayed on the screen, with correspoinding number choices.
+
+The program will function until you 'Exit', which is an option that is also displayed on the screen.
+
+Review
+The program is able to do all the functions specified on the project proposal. Input/output, conditional statements, loops, functions, arrays/strings and advanced data types were used to create this program.
+
+The way I coded it was quite different from how I imagined the game would be written. I used fout functions: the main function, a function that reads the number inputs the user selects, a function that creates new contacts and a function that does different things with the categories. I used a lot of if statements especially in the function that deals with the categories, to do different functions with the categories.
+
+Reasons for Making this Program
+I chose to do this project because I wanted to create a program that someone would be able to benefit from. I also wanted to create a program that would be quite useful, compared to other types of programs such as games. Enjoy!
