【数组和函数实战: 斗地主游戏】

void RandomCard(int num[], int numcolor[], int len);

传入牌的数组和花色,思路是先从1-53下标找一个和0下标交换,之后从2-53找一个和1下标交换,从3-53找一个和2下标交换。数值和花色都需要交换，这里需要随机数函数，在主程序先置一个随机数种子

发牌函数

void SendCard(int num[], int numcolor[],
int playnum[][PLAYCARDS],int playcolor[][PLAYCARDS],
int len);

在这里插入图片描述
由于玩家是二维数组,而卡牌是一维数组,所以需要一些计算。当第一个玩家，也就是i=0的时候，循环17次，一人17张手牌，所以赋值的卡牌下标就是0-16，当第二个玩家是，下标从17-33，当i=1时，卡牌数组num中括号里的值需要是17，所以用i 乘玩家卡牌常量PLAYCARDS，再减去多余的3张地主牌，就是 1*(20-3)+0,然后把底牌手牌也输出

选地主函数

void LandLord(int num[], int numcolor[],
int playnum[][PLAYCARDS], int playcolor[][PLAYCARDS],
int len,int *lord);

遍历玩家数组,找到红心4的拥有者,选为地主,传入地主变量的地址,接收地主编号,将地主玩家的手牌中加入底牌

开始出牌显示

void PlayShow(int playnum[][PLAYCARDS], int playcolor[][PLAYCARDS],int len,int lord);

这时分农民和地主的显示,大致和ShowCard函数的逻辑一致,只是加入了地主和农民的分辨
