Question
I need help with this program, I have started the program and I am stuck.I cannot use functions as a learning exercise, becuase I will need to do the same problem afterwards using functions.
Children often play a memory game in which a deck of cards containing matching pairs is used. The cards are shuffled and placed face down on a table. The players then take turns and select two cards at a time. If both cards match, they are left face up; otherwise, the cards are placed face down at the same positions. Once the players see the selected pair of cards and if the cards do not match, then they can memorize the cards and use their memory to select the next pair of cards. The game continues until all the cards are face up.Write a program play the memory game. Use a two - dimensional array of 4 rows and 4 columns to use a group of 16 cards with 8 matching pairs. You can use number 1 to 8 to mark the cards. Use random number genrators to randomly store the pairs in the array. I am posting the code i have started with, however I am not entirely confident with what I have is correct. #include #include #include #include using namespace std; int main(){ const int ROWSIZE = 4; const int COLSIZE = 4; int i = 0; int j = 0; int x = 0; int k = 0; int p = 0; int m = 0; int n = 0; int cardFront[ROWSIZE][COLSIZE]; char cardBack[ROWSIZE][COLSIZE]; srand(time(0)); // Displays back of cards for (i = 0; i < ROWSIZE; i++){ for (j = 0; j < COLSIZE; j++){ cardBack[i][j] = '#'; cout << cardBack[i][j]; } cout << endl; } // displays front of cards for (i = 0; i < ROWSIZE; i++){ for (j = 0; j < COLSIZE; j++){ if (i < 2){ cardFront[i][j] = COLSIZE * i + j + 1; } else{ cardFront[i][j] = (COLSIZE * i + j + 1) - 8; } cout << cardFront[i][j]; } cout << endl; } // randomizing numbers for (i = 0; i < 10; i++){ k = rand() % 4; p = rand() % 4; m = rand() % 4; n = rand() % 4; x = cardFront[k][p]; cardFront[k][p] = cardFront[m][m]; cardFront[m][k] = x; } for (i = 0; i < ROWSIZE; i++){ for (j = 0; j < COLSIZE; j++){ cout << cardFront[i][j]; } cout << endl; } return 0; }
Explanation / Answer
This game usually doesn't need two players. A single player can play the game. It's all about the number of chances he uses to lift all cards up.
This is the code for you. If you need any further modifications. Just ping me back.
