Hi,
I have the most of the program working. Problem I'm having right now is that the game ends after 3 turns, rather than checking if player has gotten 3 of his/her "X" or "O" diagonally/horizontal/vertical. Function which checks if given player wins is called "bool checkwinner(char check)". Any help would be appreciated. Thank you for your time.
Code:#include <stdio.h> #include <stdlib.h> #include <stdbool.h> char board[] = " 1 | 2 | 3\n-----------\n 4 | 5 | 6\n-----------\n 7 | 8 | 9"; // Used to display the current state of the board. int checkboard[] ={1,2,3,4,5,6,7,8,9,1,4,7,2,5,8,3,6,9,1,5,9,3,5,7}; // Used to figure out winning combinations: three blocks in a row // vertically, horizontally or diagonally // Challenge: Figure out the logic in this! bool spaces[10]; // A record of which spaces (1..9) are free(true) or taken (false) // Element 0 not used because the blocks are numbers 1..9 int nSpaces; // A count of the number of free spaces left. bool moveHandler(int player,int n); bool checkwinner(char check); int playerinput(int player); int k=0, j=0; int main(void) { int player; // Identifier of current player int key; // Key entered by user int status; bool terminationCondition; // Placeholder - to be replaced by you. player = rand() %2 +1; // Randomly choose an initial player. // Initial all spaces to be free terminationCondition = false; while (status != 1) // To be replaced by your logic for terminating a round { // Alternate between the two players if (player == 1) { player = 2; } else { player = 1; } // Print the current board printf ("\n\n %s", board); // Prompt the user for their next input key = playerinput(player); // Make the move keyed in by the user status = moveHandler(player,key); printf("%d\n",status); // Decide if you have a winner or if the game is over. } system ("pause"); return 0; } /* Implements the next move in the tic-tac-toe game * marking the square as taken * * @param player Identifier of the current player * @param space The block selected (input) by the user * @return Return true if the move is valid, false if the space is already taken */ bool moveHandler(int player,int space) { char check; int i; // set X for player one, or O for player 2 if (player == 2) { check = 'O'; } else { check = 'X'; } // Check if block(or space) is already used. If so, re-prompt the user // for another selection. while (spaces[space] == true) { printf ("\nInvalid Space"); space=playerinput(player); } // Remove block from spaces array: Make the block(or space) as taken. // Reduce the number of free-spaces by one. spaces[space]=true; //nSpaces--; // Update the display of the board by replacing the block with check mark in board // eg. Replace the number 9 with 'x' // eg. Replace the number 6 with 'o' // To convert a character into its integer equivalent use: // char aChar; // int intValue = aChar - '0'; // If aChar was character '9', then intValue will be the number 9. char chSpace = (char)(((int)'0')+space); //I didn't understand the above method so I used my own method, it converts int to char for (i==0;i<60;i++) { if (chSpace == board[i]) { board[i] = check; } } // Replace space with check mark in checkboard array if (player == 1) { checkboard[space] = 11; // this means this place is taken by player 1 } if (player == 2) { checkboard[space] = 22; //this means this place is taken by player 2 } // This will help us figure out if there is 3-in-a-row ... if we've won yet. // Run the checkwinner function return checkwinner(check); } /* Checkwinner function * * This function checks whether or not a player has a winning * combination based on the checkboard array. * @param check The character for the current player's turn (x or o) * @return True if the player has 3-in-a-row; false otherwise. */ bool checkwinner(char check) { // Set the array element variables int i; for (i=1;i<24;i++) { printf("%d ",checkboard[i]); } // Loop through checkboard to check winner if (checkboard[0] == 11) { k++; } if (checkboard[0] == 22) { j++; } for (i=1;i<24;i++) { if (i%3 == 0) { k = 0; j = 0; } if (checkboard[i] == 11) { k++; } if (checkboard[i] == 22) { j++; } if (k == 3) { return true; } if (j == 3) { return true; } else { return false; } } } /* Prompts the player for their choice of block * @param player Identifier of current player * @return The number of the block that they want to put an 'x' or 'o' in. (1..9) */ int playerinput(int player) { int key; do { printf ("\n\nPlayer %d : Please select a space ", player); int status = scanf("%d",&key); } while ( (key<1) && (key>9) ); return key; }
