The Objective
The objective of this assignment is for you to practice good design
techniques (top-down design that has appropriate use of functions that
minimize coupling and maximize cohesion) and to become familiar with using
two-dimensional arrays and structures.
The Background
The State of Maryland has a gambling game called KENO. In this project,
you will simulate playing KENO, but with slightly easier rules.
For each game of KENO, 20 numbers are chosen randomly from the range of values
1 to 80 and displayed in a grid on a screen. Four rows and five columns are
used to display the 20 values. No duplication of numbers are allowed in
these values.
In order to play KENO, the player fills out a slip. On the slip s/he must
first decide whether s/he wants to try to match only 1 of the 20 numbers, or 2,
or more. The number of matches you are trying to make is called the spot. So
if the player wants to bet that he can match 4 of the 20 numbers, it is said
that he's playing a 4 spot game. The player can choose to play a 1 spot game
up to a 10 spot game.
Next the player must decide how much to wager. He can choose to bet $ 1, $ 2,
$ 3, $ 4, $5, $ 10, or $ 20 per game. The chart shown below will show the
prize value per dollar wagered.
Next the player must choose the numbers he thinks will come up. Obviously,
if the player is playing a 3 spot game, he must enter 3 numbers; a 7 spot game,
7 numbers, etc. You must do error checking on the user's input so that
s/he does not give duplicate numbers or numbers that are not in the range of 1
to 80, inclusive. In the real KENO game, if you are playing the 3 (or more)
spot game, you can win smaller prizes than those shown in the chart below for
matching fewer number than the spot of the game. In our modified version, the
player must match all 3 numbers to win a 3 spot game. The payouts are shown in
the chart below.
KENO Payout Chart
<![CDATA[
1 spot game match 1 to win $ 2 per $ 1 bet
2 spot game match 2 to win $ 10 per $ 1 bet
3 spot game match 3 to win $ 25 per $ 1 bet
4 spot game match 4 to win $ 50 per $ 1 bet
5 spot game match 5 to win $ 300 per $ 1 bet
6 spot game match 6 to win $ 1000 per $ 1 bet
7 spot game match 7 to win $ 2500 per $ 1 bet
8 spot game match 8 to win $ 10000 per $ 1 bet
9 spot game match 9 to win $ 25000 per $ 1 bet
10 spot game match 10 to win $ 100000 per $ 1 bet
]]>
Finally, the player must choose how many consecutive Keno games he wants to
play using those numbers. S/he may chose 1, 2, 3, 4, 5, 10 or 20 consecutive
games.
The real KENO also gives the user the option of playing a bonus, but our
version won't deal with bonuses.
The Task
You are to write a program that simulates the playing of KENO, using the
CMSC 201 modifications stated above. These modifications will make the
coding of the project easier.
You must use a structure to hold the information found on a slip.
Here is the structure definition you are required to use :
<![CDATA[
typedef struct slip
{
int spots;
int wager;
int picks[10];
int games;
} SLIP;
]]>
You must use a two-dimensional array of 4 rows and 5 columns to hold the
numbers that are drawn for a single game. Remember no duplicates are allowed.
Your program must calculate the cost of a slip and ask the user for that much
money as well as determine whether the customer is a winner and calculate how
much his winnings are.
The user can continue to play as long as s/he wants. After each group of
consecutive games the user is given the choice to quit or continue playing.
To quit the user must enter -1. To continue the user can enter any other
integer.
To make grading easier, you must get the seed for the random number generator
from the user rather than getting the seed with a call to time. The random
number generator should be seeded only one time at the very beginning of your
program (Not within any loop). The user's response to the prompt "Please
enter any positive integer to begin playing" is to be used as the seed to the
random number generator.
Since we are using the same machine with the same operating system, if you
use the same seed as I did in the sample run, 7, then the numbers produced
by the random number generator will be identical to the ones I got. Use the
modulus technique to modify those values to be within the range of 1 to 80,
inclusive. When I get a number which is a duplicate, I don't use it and
immediately get another random number to use instead. You must use this
method to produce your sets of twenty numbers per game so that your program's
output will match mine exactly
You will keep track of the total number of games played, the total winnings,
and whether the player has broken even, is ahead by how much, or is in the
hole by how much. These totals should be shown to the user just before asking
if s/he wants to play again.
You are to use separate compilation for this project. You may have as many .c
and .h files as you feel are necessary. Group your functions according to
their use into appropriately named files.
My Guarantee
I guarantee that all of the input used by the graders will be integers.
