CS 11 MACHINE PROBLEM 1DUE DATE: JANUARY 31 2013, 12 mn

GENERAL INSTRUCTIONS

1) Your submission should be a zipped file named CS 11 MP 1 .zip and submitted via e-mail to janmichaelyap@gmail.com. The contents should be your source codes (.c files) and a PDF file containingthe external documentation of your codes.

2) The source code should also contain documentations herewith. An undocumented or poorly documented source code may incur demerits.

3) Apart from your source code and the by-products, an external documentation should also included. The external documentation should contain the following sections:

Implementation In this section, you are to describe how the solution to the problem is implemented. You may use plain declarative paragraphs, a pseudocode (NOT your source code), or a flowchart depicting the algorithm / procedure you used for the problem.

Function Description In formulating a program, you may have created some functions to implement some parts of the code. In this section, list down all the functions created and a brief description of what each does.

Resources (Optional) If you have consulted books, journals, web pages, and/or resource persons (IF ANY) in coming up with the program, kindly cite them in this section. This section is optional, that is, this section maybe omitted if you have independently, and without any external assistance, formulated the solution.

User Manual A brief tutorial on what your program can do and how to go about with your program.

4) The criteria for grading your MP submission is as follows: Functionality (60 pts.) - If a program works for all test inputs Documentation (30 pts.) - If your program is well documented, i.e. vital aspects of your program

have been properly described and explained Code Design (10 pts.) - If coding conventions (variable naming, indentations, etc.) are properly

followed

5) Assume correct input for all the problems.

6) Should there be any doubts, questions, and other feedbacks, email me at janmichaelyap@gmail.com or consult me during class and / or consultation hours.

7) Any form of violations to intellectual property rights would be dealt with accordingly as stated in the course requirements and rules section of the syllabus.

MACHINE PROBLEM TITLE: CODE BREAKER

The program would initially generate a four digit random number with distinct digits, i.e., no 2 digits are the same and each digit in that number is unique. To help you with this, consult references regarding the use of the srand function (You can use this as starting point: http://stackoverflow.com/questions/1190689/problem-with-rand-in-c). Afterwards, the user would be prompted to guess that four digit number. The program would provide clues by giving a number of black and white markers. A black marker is given for an exact number within the target that is correctly placed in the proper position. A white marker on the other hand, notifies the user that a correct number is guessed, but placed in the wrong position. If an input consists of repeated digits, and that particular digit is part of the target, remember that a black marker over rules a white marker, assuming that one of the repeated digits is placed over the correct position. Otherwise, only 1 white marker is given. The user would be given 7 chances to guess that number after which the program would then reveal the target number. If the user guesses the number and the exact positions correctly, a notification would also be printed and the program terminates.

Sample run:

Assume target number is 1725

Chance # 1Enter guess> 43122 white0 black

Chance # 2Enter guess> 37111 white1 black

Chance # 3Enter guess> 17110 white2 black

Chance #4Enter guess> 17321 white2 black

Chance #5Enter guess> 17230 white3 black

Chance #6Enter guess> 1725YOU WIN!!!

Sidetask 1 (+5 pts.): Provide the user an option to change the difficulty of the game based on the number of tries that will be given with the following options: Easy (10 chances), Average (7 chances), and Difficult (5 chances).

Sidetask 2 (+10 pts.): When playing the game, if the user enters the Konami code by pressing the up arrow key twice, then pressing the down arrow key twice, left arrow key, right arrow key, left arrow key, right arrow key, 'b' key, then finally the 'a' key, then your program should reveal the target number which the user can input to win the game.
