[C语言] 发牌洗牌

C语言发牌洗牌

1.模拟发牌程序
通过写两个函数模块来编写洗牌程序和打印的发牌程序

2.编写洗牌程序

void shuffle(char cards[][10],int n){
    
	int i=54;
	char ca,cb,ct[10];
	srand((unsigned)time(NULL));
	
	while(i--){
    
		ca=rand()%54;
		cb=rand()%54;
		
		strcpy(ct,cards[ca]);
		strcpy(cards[ca],cards[cb]);
		strcpy(cards[cb],ct);		
	}
		
}

3.编写打印的发牌程序

void printCard(char cards[][10],int n){
    
	int i,rn=0;
	printf("第一个人:\n");
	for(i=0;i<17;i++){
    
		if(rn%5==0)
			printf("\n");
		rn++;
		printf("%s ",cards[i]);		
	}
	printf("\n\n第二个人:\n");
	rn=0;
	for(i=17;i<33;i++){
    
		if(rn%5==0)
			printf("\n");
		rn++;
		printf("%s ",cards[i]);		
	}
	printf("\n\n第三个人:\n");
	rn=0;
	for(i=33;i<50;i++){
    
		if(rn%5==0)
			printf("\n");
		rn++;	
		printf("%s ",cards[i]);	
	}
	printf("\n\n底牌:\n");
	for(i=51;i<54;i++){
    
		printf("%s ",cards[i]);		
	}
	printf("\n");
	getchar();
}

4.在主函数预定义和调用

main(){
    
	system("color 0f");
	char cards[][10]={
    
	"红桃 2","红桃 3","红桃 4","红桃 5","红桃 6","红桃 7","红桃 8","红桃 9","红桃 10","红桃 J","红桃 Q","红桃 K","红桃 A",
	"方块 2","方块 3","方块 4","方块 5","方块 6","方块 7","方块 8","方块 9","方块 10","方块 J","方块 Q","方块 K","方块 A",
	"梅花 2","梅花 3","梅花 4","梅花 5","梅花 6","梅花 7","梅花 8","梅花 9","梅花 10","梅花 J","梅花 Q","梅花 K","梅花 A",		
	"黑桃 2","黑桃 3","黑桃 4","黑桃 5","黑桃 6","黑桃 7","黑桃 8","黑桃 9","黑桃 10","黑桃 J","黑桃 Q","黑桃 K","黑桃 A",
	"大王","小王" 
	};
	int n = 54;
 
	shuffle(cards,n);
	printCard( cards, n);
		
return 0;
}

5.最终程序

#include<stdio.h>
#include<string.h>
#include<stdlib.h> 
#include<time.h>
void shuffle(char cards[][10],int n);
void printCard(char cards[][10],int n);

main(){
    
	system("color 0f");
	char cards[][10]={
    
	"红桃 2","红桃 3","红桃 4","红桃 5","红桃 6","红桃 7","红桃 8","红桃 9","红桃 10","红桃 J","红桃 Q","红桃 K","红桃 A",
	"方块 2","方块 3","方块 4","方块 5","方块 6","方块 7","方块 8","方块 9","方块 10","方块 J","方块 Q","方块 K","方块 A",
	"梅花 2","梅花 3","梅花 4","梅花 5","梅花 6","梅花 7","梅花 8","梅花 9","梅花 10","梅花 J","梅花 Q","梅花 K","梅花 A",		
	"黑桃 2","黑桃 3","黑桃 4","黑桃 5","黑桃 6","黑桃 7","黑桃 8","黑桃 9","黑桃 10","黑桃 J","黑桃 Q","黑桃 K","黑桃 A",
	"大王","小王" 
	};
	int n = 54;
 
	shuffle(cards,n);
	printCard( cards, n);
		
return 0;
}

void shuffle(char cards[][10],int n){
    
	int i=54;
	char ca,cb,ct[10];
	srand((unsigned)time(NULL));
	
	while(i--){
    
		ca=rand()%54;
		cb=rand()%54;
		
		strcpy(ct,cards[ca]);
		strcpy(cards[ca],cards[cb]);
		strcpy(cards[cb],ct);		
	}
		
}

void printCard(char cards[][10],int n){
    
	int i,rn=0;
	printf("第一个人:\n");
	for(i=0;i<17;i++){
    
		if(rn%5==0)
			printf("\n");
		rn++;
		printf("%s ",cards[i]);		
	}
	printf("\n\n第二个人:\n");
	rn=0;
	for(i=17;i<33;i++){
    
		if(rn%5==0)
			printf("\n");
		rn++;
		printf("%s ",cards[i]);		
	}
	printf("\n\n第三个人:\n");
	rn=0;
	for(i=33;i<50;i++){
    
		if(rn%5==0)
			printf("\n");
		rn++;	
		printf("%s ",cards[i]);	
	}
	printf("\n\n底牌:\n");
	for(i=51;i<54;i++){
    
		printf("%s ",cards[i]);		
	}
	printf("\n");
	getchar();
}
