C语言小程序（七）、石头剪刀布

本来挺简单的一个程序，但突然想把《Friends》给糅合进去，就多花了一些心思，这是我写过最有趣的程序了。

#include <stdio.h>
#include <stdlib.h>
#include <time.h>
 
int getrand()
{
	srand(time(NULL));
	return rand()%3;
}
 
int win_lose(int choice)
{
	int rand = 0;
	char *p[3] = {"SCISSORS", "STONE", "CLOTH"};
	rand = getrand();
	printf("\nThe system give the %s.\n",p[rand]);
	rand++;
 
	if(choice == rand)							//even
	{
		printf("\nJoey:\tHei, How you doing? We call it even, all right?\n");
		printf("\tAnd if you are Chandler M. Bing, of course you will say ok.\n");
		return 0;
	}
	else if(rand==choice-1 || rand==choice+2)	//win
	{
		printf("\nMonica:\tOf course the winner is Me. I knew it, you such a loser,\n");
		printf("\tyou can't win me ever!\n");
		printf("Ross:\tIt can't be, I am Profess Geller and I am a doctor.\n");
		printf("\tI can't lose, you must cheat me last time. \n");
		return 1;
	}
	else										//lose
	{
		printf("\nRachel:\tOh my god! Oh my god! I can't believe this. Phoebe,\n");
		printf("\tyou are my best friend, can we forget this?\n");
		printf("Phoebe:\tOk, But it is when you say that you don't love Ross any more.\n");
		return -1;
	}
}
 
int main()
{
	int choice = 0;
	int flag = 0;
	int rot = 0;
	char ch;
	system("clear");
	printf("***********************************************");
	printf("\n\tLets play a game about <Friends>.\n");
	printf("***********************************************");
	printf("\nJanice:\tYou don't want to see me any more, right? \n\tSo just chose a number quickly:\n");
	printf("\n1.SCISSORS\n2.STONE\n3.CLOTH\n");
	do
	{
		printf("\nInput your choice:");
		scanf("%d",&choice);
		if(choice>0 && choice<4)
		{
			flag = win_lose(choice);
			while((ch=getchar())!='\n' && ch!=EOF);
			printf("\nGunther:I want to see Rachel");
			if(flag == -1)
				printf(" again");
			printf(", so please replay it.(y/n)");
		}
		else
		{
			while((ch=getchar())!='\n' && ch!=EOF);
			printf("\nMonica:\tWhat's the matter with you! What you need is just chose\n");
			printf("\ta number from 1 to 3. So are you ready?(y/n)");
		}
 
		ch = getchar();
	}
	while(ch=='y' || ch=='Y' || ch=='\n');
 
	printf("\nGoodbye！\n");
 
	return 0;
}

谨以此程序纪念下《Friends》，Monica、Ross、Joey、Rachel、Chandler、Phoebe。

还请诸位大侠自动忽略那蹩脚的英语。
