刽子手游戏。题目较长,理解以后很容易…

就是猜词游戏,输入电脑给的字符串题目和玩家猜测的单词,如果答案中有这个单词,则所有的该单词都会显示出来,有7次机会,猜曾经猜对的单词算错。

注意:重复猜算错,所以把猜对的赋值为’ ‘   空格。

#include <cstdio> 
#include <cstring>
#include <iostream> 
#include <fstream>
using namespace std;


const char *s[]={"You lose.","You win.","You chickened out."};


int guess(string sa,string sg){	//返回0失败,1成功。2放弃 
	int bin=0;	    //是否猜中	
	int chance,left; 
	chance = 7;
	left = sa.size();	
	for (int i = 0;i < sg.size(); i++){
		bin=0;
		for(int j = 0; j < sa.size();j++){
			if(sg[i]==sa[j]){
				sa[j] = ' ';				
				left--;
				bin=1;
			}
		}
		if(bin == 0){   //没有猜中 
			chance--;
		}
		
		if(chance == 0) return 0;
		else if(left == 0) return 1; 
	} 
	return 2;
}


int main(){
	int t;
	string sa,sg;
	ifstream cin("UVa489.txt");
	
	while(cin>>t&&t&&t!=-1){
		
		cin>>sa>>sg;
	    int status = guess(sa,sg); 
		
		printf("Round %d\n",t);
		printf("%s\n",s[status]);

		sa.clear();sg.clear();
	}
	
	return 0;
}
