C语言学习 / 简易21点

游戏规则：玩家电脑各发2张牌，玩家两张牌均为明牌，电脑一明一暗；玩家根据点数大小选择是否继续要牌，当玩家点数为21点时玩家直接获胜，超过21点电脑获胜；当玩家选择不要牌，开始电脑回合，电脑点数大于21点玩家获胜，电脑点数大于等于玩家，电脑获胜。

1、打印欢迎界面 int main() { playgame(); return 0; } void playgame() { int input = 0; do { welcome(); printf("请选择:>"); scanf("%d", &input); switch (input) { case 1: printf("开始游戏\\n"); break; case 0: printf("退出游戏\\n"); break; default: printf("选择错误，请重新选择\\n"); break; } } while (input); } void welcome() { printf("******************************\\n"); printf("********** 21点 *************\\n"); printf("*** 1.play 0.exit ***\\n"); printf("******************************\\n"); }

2、打印牌池和初始手牌 

（1）添加game（）函数

void playgame() { int input = 0; do { ... ... { case 1: printf("开始游戏\\n"); game(); break; ... ... } } while (input); }

 （2）创建game.h 和 game.c 用于游戏主程序

//text.c

#include "game.h" void game() { int board[ROW][COL] = { 0 }; int PlayerCard[13] = { 0 }; int ComputerCard[13] = { 0 }; initial(board, ROW, COL, PlayerCard, ComputerCard); show(board, ROW, COL); Computer(board, ROW, COL, ComputerCard); Player(board, ROW, COL, PlayerCard); }

 //game.h

#define ROW 4 #define COL 13 #include<stdio.h> #include<time.h> #include<Windows.h> void initial(int board[ROW][COL], int row, int col, int PlayerCard[],int ComputerCard[]); void show(int board[ROW][COL], int row, int col); void Computer(int board[ROW][COL], int row, int col,int ComputerCard[]); void Player(int board[ROW][COL], int row, int col, int PlayerCard[]);

//game.c

#include"game.h" void initial(int board[ROW][COL], int row, int col, int PlayerCard[], int ComputerCard[]) { int i = 0; int j = 0; for (i = 0;i < row;i++) { for (j = 0;j < col;j++) { if (j < 9) board[i][j] = j + 1; else board[i][j] = 10; } } for (i = 0;i < 13;i++) { PlayerCard[i] = 0; ComputerCard[i] = 0; } } void show(int board[ROW][COL], int row, int col) { int i = 0; int j = 0; printf("牌池：\\n"); for (i = 0;i < row;i++) { for (j = 0;j < col;j++) { printf("%d ", board[i][j]); } printf("\\n"); } } int give(int board[ROW][COL], int row, int col) { int card = 0; while (1) { int i = rand() % row; int j = rand() % col; if (board[i][j] != 0) { card = board[i][j]; board[i][j] = 0; break; } } return card; } void Computer(int board[ROW][COL], int row, int col,int ComputerCard[]) { int i = 0; int flag = 0; ComputerCard[0] = give(board, ROW, COL); ComputerCard[1] = give(board, ROW, COL); Sleep(300); printf("电脑手牌:[?] %d\\n", ComputerCard[1]); } void Player(int board[ROW][COL], int row, int col,int PlayerCard[]) { int i = 0; int flag = 0; PlayerCard[0] = give(board, ROW, COL); PlayerCard[1] = give(board, ROW, COL); Sleep(300); printf("玩家手牌:%d %d\\n", PlayerCard[0], PlayerCard[1]); }

3、玩家回合 

（1）创建round（）函数

//test.c

void game() { ... ... Player(board, ROW, COL, PlayerCard); Round(board, ROW, COL, PlayerCard, ComputerCard); }

//game.h

void Round(int board[ROW][COL], int row, int col, int PlayerCard[], int ComputerCard[]);

//game.c

int test(int Card[], int time) { int i = 0; int sum = 0; for (i = 0;i < time;i++) { sum += Card[i]; Sleep(300); printf("%d ", Card[i]); } printf("\\n"); return sum; } void Round(int board[ROW][COL], int row, int col, int PlayerCard[], int ComputerCard[]) { int input = 0; int time_P = 2; int sum_P = PlayerCard[0] + PlayerCard[1]; int i = 0; printf("玩家回合开始\\n"); do { printf("玩家是否继续要牌？1.是 0.否>>"); scanf("%d", &input); switch (input) { case 1: sum_P = 0; PlayerCard[time_P] = give(board, ROW, COL); time_P++; printf("玩家手牌："); sum_P = test(PlayerCard, time_P); if (sum_P > 21) { printf("玩家点数为%d，超过21点，电脑获胜!\\n", sum_P); input = 0; } if (sum_P == 21) { printf("玩家点数为21点，玩家获胜！\\n"); input = 0; } break; case 0: printf("玩家回合结束，电脑回合开始\\n"); break; default: printf("选择错误，请重新选择\\n"); break; } } while (input); }

4、电脑回合 

(1)代码实现

//game.c

void Round(int board[ROW][COL], int row, int col, int PlayerCard[], int ComputerCard[]) { case 0: printf("玩家回合结束，电脑回合开始\\n"); Sleep(300); printf("玩家手牌："); for (i = 0;i < time_P;i++) { printf("%d ", PlayerCard[i]); } printf("\\n"); Sleep(300); printf("电脑手牌：%d %d\\n", ComputerCard[0], ComputerCard[1]); C_Round(board, ROW, COL, PlayerCard, ComputerCard, time_P, sum_P); break; } void C_Round(int board[ROW][COL], int row, int col, int PlayerCard[], int ComputerCard[], int time_P, int sum_P) { int i = 0; int time_C = 2; int sum_C = ComputerCard[0] + ComputerCard[1]; while (sum_C < sum_P && sum_C < 21) { ComputerCard[time_C] = give(board, ROW, COL); time_C++; Sleep(500); printf("电脑手牌："); sum_C = test(ComputerCard, time_C); } if (sum_C > 21) { printf("电脑点数为%d，超过21点，玩家获胜！\\n", sum_C); } else if (sum_C >= sum_P) { printf("电脑点数为%d,玩家点数为%d，电脑获胜！\\n", sum_C,sum_P); } }

5、设置筹码 

（1）代码实现

//game.h

#define CHIP 1000 void Round(int board[ROW][COL], ..., int ComputerCard[],int* chip);

//test.c

int chip = CHIP; void playgame() { int input = 0; do { if (chip <= 0) { printf("没有足够的筹码进行下一轮游戏，游戏结束！\\n"); break; } welcome(); ... ... } while (input); } void game() { ... ... show(board, ROW, COL); printf("玩家筹码：%d\\n", chip); ... Player(board, ROW, COL, PlayerCard); Round(board, ROW, COL, PlayerCard, ComputerCard, &chip); printf("玩家筹码：%d\\n", chip); }

//game.c

void C_Round(int board[ROW][COL], ..., int sum_P, int* chips) { ... ... if (sum_C > 21) { ... *chips += 90; } else if (sum_C >= sum_P) { ... *chips -= 100; } } void Round(int board[ROW][COL], ..., int ComputerCard[],int *chip) { ... ... int chips = *chip; printf("玩家回合开始\\n"); do { ... ... switch (input) { case 1: ... ... if (sum_P > 21) { ... *chip -= 100; ... } if (sum_P == 21) { ... *chip += 90; ... } break; case 0: ... ... C_Round(board, ..., sum_P, &chips); *chip = chips; break; ... ... } } while (input); }
