Programming Homework: Rigging a deck of cards in C -
i have assignment i've been working on. supposed have deck of cards , distribute evenly 4 players.
each card has own value (two = 1, three=2, ..., king=12, ace=13) , suit has own value (clubs = 1, diamonds = 2, hearts = 3, spades = 4)
i'm supposed make dealer (player p) win 75% of time swapping out cards, or along lines. program wrote emulates cards having single array 0 51. program runs, command prompt says "press key continue ..."
can please @ code , tell me if there's might causing this? in advance.
#include "stdafx.h" #include <stdio.h> #include <stdlib.h> #include <time.h> #include <string.h> #include <algorithm> #define deck 52 #define cards 52 #define suits 4 #define faces 13 int deck[deck]; void distributecards(int i); void swap(int i, int j); void shuffle(unsigned int wdeck[][faces]); int main(void) { int deck[deck] = { 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51 }; } void swap(int i, int j) { int temp = deck[i]; deck[j] = deck[i]; deck[i] = temp; } int max(int i, int j, int k, int l) { int tempmax = deck[i]; int maxindex = i; if (deck[j] > tempmax) { tempmax = deck[j]; maxindex = j; } if (deck[k] > tempmax) { tempmax = deck[k]; maxindex = k; } if (deck[l] > tempmax) { tempmax = deck[l]; maxindex = l; } return maxindex; } int determineface(int i) { if (i % 4 == 0) return 3; // 3 = hearts if (i % 4 == 1) return 2; // 2 = diamonds if (i % 4 == 2) return 4; // 4 = spades else return 1; // 1 = clubs } int determinevalue(int i) { if (i / 4 == 0) return 1; // 1 = 2 if (i / 4 == 1) return 2; // 2 = 3 if (i / 4 == 2) return 3; // 3 = 4 if (i / 4 == 3) return 4; // 4 = 5 if (i / 4 == 4) return 5; // 5 = 6 if (i / 4 == 5) return 6; // 6 = 7 if (i / 4 == 6) return 7; // 7 = 8 if (i / 4 == 7) return 8; // 8 = 9 if (i / 4 == 8) return 9; // 9 = ten if (i / 4 == 9) return 10; // 10 = jack if (i / 4 == 10) return 11; // 11 = queen if (i / 4 == 11) return 12; // 12 = king else return 13; // 13 = ace } void distributecards() { int house[13]; // house = player p int p1[13]; // p1 = player q int p2[13]; // p2 = player r int p3[13]; // p3 = player s //picking house's cards printf("\n\nplayer p's cards: \n"); (int = 0; < 13; i++) { int rand1 = (rand() % (51 - i)) + i; int rand2 = (rand() % (51 - i)) + i; int rand3 = (rand() % (51 - i)) + i; int rand4 = (rand() % (51 - i)) + i; int rand = max(rand1, rand2, rand3, rand4); house[i] = deck[rand]; swap(rand, i); } //picking p1's cards printf("\n\nplayer q's cards: \n"); (int = 13; < 26; i++) { int rand5 = (rand() % (51 - i)) + i; p1[i - 13] = deck[rand()]; swap(rand(), i); } //picking p2's cards printf("\n\nplayer r's cards: \n"); (int = 26; < 39; i++) { int rand6 = (rand() % (51 - i)) + i; p2[i - 13] = deck[rand()]; swap(rand(), i); } //picking p3's cards printf("\n\nplayer s's cards: \n"); (int = 39; < 51; i++) { int rand7 = (rand() % (51 - i)) + i; p3[i - 13] = deck[rand()]; swap(rand(), i); } }
the behavior fine. have written main function:
int main(void) { int deck[deck] = {....}; } which nothing except defining array. no input, no output, nothing. "press key continue" means array defined correctly , destroyed correctly , program run correctly , terminated.
edit:
i think need like:
int main(void) { int deck_temp[deck] = { 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51 }; memcpy(deck, deck_temp, 52*sizeof(int)); distributecards(); }
