Please implement a basic version of Tic Tac Toe:
1. Function main and function headers are provided. Please implement the functions and do not change the main.
2. Our program must produce identical output: ASMT02_PA_Run1.txt
and ASMT02_PA_Run2.txt
PART B – Credit Card Number Validation, 10 points
Credit card numbers follow certain patterns. A credit card number must have
between 13 and 16 digits. The starting numbers are: 4 for Visa cards, 5 for
MasterCard cards, 37 for American Express cards, and 6 for Discover cards.
Example: Validating 4388576018402626
a) Double every second digit from right to left. If doubling of a digit results
in a two-digit number, add the two digits to get a single digit number.
b) Now add all single-digit numbers from Step a:
4 + 4 + 8 + 2 + 3 + 1 + 7 + 8 = 37
c) Add all digits in the odd places from right to left in the card number:
6 + 6 + 0 + 8 + 0 + 7 + 8 + 3 = 38
d) Sum the results from Step b and Step c:
37 + 38 = 75
e) If the result from Step d is divisible by 10, the card number is valid;
otherwise, it is invalid.
Please implement Credit Card Number Validation:
1. Function main is provided. Please implement isvalidcc and other
functions which you may add to the program.
2. Please do not change function main
3. Your program must produce identical output: ASMT02_PB_Run.pdf

PART C – Dictionary 340 C++, 35 points
Our satisfied clients are back to ask us to implement another interactive dictionary. Our dictionary takes input from users
and uses the input as search key to look up values associated with the key. Requirements:
– Coding: No hard coding, https://en.wikipedia.org/wiki/Hard_coding . Please think (even more) Dynamic and Scalable.
– Data Source: a text file, Data.CS.SFSU.txt . Please think Software Deployment and Usability.
– Data Structure: Use existing data structure(s) or create new data structure(s) to store our dictionary’s data. Each keyword,
each part of speech, and each definition must be stored in a separate data field. Do not combine them such as storing
three parts in one String.
– Data Loading: When our program starts, it loads all the original data from the data source into our dictionary’s data
structure. The data source file is opened once and closed once per run. It must be closed as soon as possible. It must be
closed before our program starts interacting with users.
– User Interface: A program interface allows users to input search keys. This interface then displays returned results. Our
program searches the dictionary’s data (not the data source text file) for values associated with the search keys.
– Identical Output: Our program’s output must be identical to the complete sample run’s output: ASMT02_PC_Run.pdf
1. Program Analysis to Program Design, 10 points
In 1 full page, please explain the following in detail:
▪ Your analysis of the provided information and the provided sample output. Compare to the ASMT 01 Java version.
▪ What problem you are solving. How it is different from that of ASMT 01. Problem formulation and problem solving.
▪ How you load data from the data source. What the steps are. Why these steps. Can you do better?
▪ Which data structure(s) you use/create for your dictionary. And why. Think Data Structures and think Data Design.
2. Program Implementation, 25 points
▪ Does your program work properly?
▪ How will you improve your program?
▪ Sample run (not the complete run. Please remember to use the complete output.):
