# Color Puzzle Game

Topic : Character Code Logic Game

Background:
Colour code logic game uses coloured shapes see-through tiles to form a pre-defined
formation. The player is required to stack a rack of tiles to recreate the exact composition. Itrequires logical thinking to combine shape, colour, order and decide which way round eachtile needs to be placed to solve a given puzzle. The game aims to develop logical thinkingskills, strategic planning and visual / spatial perception.

To develop a stand-alone program with C that simulates Colour Code Logic game. The goal of thisprogram is to rearrange character tiles to solve a puzzle.

Specification & Requirement:
· Develop a 2-dimensional array in C to form a tile formation by using a selected character. You
are free to select the character and size of the tile for your game. The minimum requirement for
the tile size is 11 rows by 11 columns. The game should consist of minimum of four tiles.

• You are allowed to design your own tile with characters, alphabets, numbers, colours (optional)or a combination of them. The pattern of your tile should NOT be formed randomly, you mustdesign the pattern of your tile first, then code it by using loop structure as much as you can.
· You are expected to design your own mechanism of generating the formation of your tiles. It
should be documented in your design report to elaborate the details of your mechanism.
· The game will then generate a puzzle for player to solve by placing the available tiles randomlyon top of each other. The goal of the game is for the player to place the tiles in the order thatwill to recreate the exact composition of the given puzzle.
· You may also set your own rules for your game, such as the way a block is chosen and placed.
· The performance of the player may be measured by counting the number of attempts taken to
solve the puzzle.
· Each element of array contains the following suggested attributes :
o a variable of character to form the tile
o and any other attributes you think appropriate to your program
Thus, the element can be described as “struct” of array in the C programming language.
· You are expected to design your own structure for your program, and it should be documented
in your design report to elaborate the details by listing all the functions and a brief description
of them, which may include explanation / justification on the way you decompose your program
into those functions / modules.
· The record of previous players is stored in a plain text data file. The information of all the
previous players should be displayed at the beginning of the game. User / player will also be
prompted to key in their information, and that information will then be stored in the same text
file.
· Input to the system is through a DOS command window.
· This program must first prompt the user (in the command window) for the next action to be
carried out. The user should be able to terminatethe program at any time.
· Output should be printed on DOS window to show the latest layout of the board.
· The program codes MUST be in functions. DO NOT write all the code in the “main()” function.
· Must NOT use global variable and goto in the program.
· Graphical window interface can be used as an alternative (optional)
· This C program is recommended to be written in Code∷Blocks or Quincy 2005.

Procedure of Program Development

Use an iterative process (spiral or prototype SDLC) to design and implement a solution to your
program. That means
1. write a small program to do a little bit of the problem
a. compile and run the small program
2. next, add a function or two
a. compile and run the improved program
3. repeat step 2 until you are done

### DESIGN REPORT:

1).Design of the Tiles

Tile 1: Lower Half of the Tile is filled with *  that is,

Tile[i][j] = ‘*’ if j > 5.

This can be done by running a loop in i from 6 to 10 which contains a sub-loop in j which runs from  0 to 10, in each iteration set Tile[i][j] = ‘*’.

Tile 2: Contains 2 vertical equi-spaced lines.

This can be done by running a loop in i from 0 to 10, in each  iteration set Tile[i] = ‘+’ and then run another loop in I from 0 to 10 , in each  iteration set Tile[i] = ‘+’.

Tile 3: Contains 2 Horizontal equi-spaced lines and a mid vertical line.

Developing Horizontal lines is similar to Developing Vertical lines in Tile 2. Mid Vertical line can be made by a loop in i from 0 to 10, in each iteration set Tile[i] = ‘\$’.

Tile 4: Contains a filled Rhombus, whose sides are the lines joining the mid-points of the sides of the Tile.

2). User Manual

The Program first prints the previous attempts made by all the Players. Then it asks for the name of the Player. It then shows are the 4 tiles and creates Puzzle.

The Player has to Stack the tiles one over the other so that the top view of the Stack resembles the Puzzle.

If Player successfully stacks the tiles It prints CORRECT else it prints WRONG

3). Program Design

·         The Design of the Program is so made to have as much less code in the main function

·         Each of the tile is designed as a\described in the tile design part.

·         Random order of Tiles is needed to create the problem puzzle this is done by the following Algorithm

To shuffle an array a of n elements (indices 0..n-1):

for i from n – 1 downto 1 do

j = random integer with 0 <= j <= i

exchange a[j] and a[i]
