Memory Matching Game
Adapted from Problem Solving with C++, Seventh Edition by Walter
The goal of this program is to work with two-dimensional arrays.
A common memory matching game played by young children is to start with
a deck of cards that contain identical pairs. For example, given six
cards in the deck, two might be labeled "1," two might be labeled "2,"
two might be labeled "3." The cards are shuffled and placed face down
on the table. The player then selects two cards that are face down,
turns them face up, and if they match they are left face up. If the two
cards do not match, they are returned to their original position face
down. The game continues until all cards are face up.
Write a program that plays the memory matching game. Use 16 cards that
are laid out in a 4 x 4 square and are labeled with pairs of numbers
from 1 to 8. Your program should allow the player to specify the cards
they would like to select through a coordinate system.
For example, suppose the cards are in the following layout:
All of the cards are face down except the pair 8, which has been
located at the coordinates (1,1) and (2,3). To hide the cards that have
been temporarily place face up (but do not match), output a large
number of newlines to force the old board off the screen (you may want
to wait to do this until after you have finished debugging).
- Use a two-dimensional array for the arrangement of the cards.
- Use a two-dimensional array that indicates if a card is face up
- Write a function that initializes and "shuffles" the cards
in the array by
repeatedly (say 10000 times) selecting two cards at random and swapping
- Write a function that generates the screen display.
Here are strongly suggested, but not required prototypes for the two
ShowCards(int cards[LENGTH], bool faceup[LENGTH]);
Here is the required
comment format for at least the
two functions required above and any tother significant
functions (courtesy of Dr. Sarraille):
(Some notes on generating pseudo random numbers in C++)
These functions are found in the cstdlib, so you will need to include
it in your program. You will also need: #include <time.h> to seed
the random number generator. You should look these functions up in your
favorite C++ reference to get a better understanding of their
// Initialize random number generator using
// the current value of the clock
// to generate a random number between 1 and 365:
// (random may not be available in all implementations, so rand is
What to Submit
Name your source code file memory_match.cpp and your script
Your script should show how you
compiled your program and 2 - 4 turns/trys of your program.
