C++11代码如下：

#include<iostream>
#include<string.h>
using namespace std;
char ans[100], test[100];

int main() {
    int rnd;
    while ((cin>>rnd>>ans>>test)&&rnd!=-1) {
        cout << "Round " << rnd << endl;
        int chance = 7;
        int left_ch = strlen(ans);
        for (int i = 0; i < strlen(test); i++) {
            bool bad = true;
            for (int j = 0; j < strlen(ans); j++) {
                if (ans[j] == test[i]) {
                    ans[j] = ' ';
                    left_ch--;
                    bad=false;
                }
            }
            if (bad) --chance;
            if (!(left_ch && chance)) break;
        }
        if (!left_ch) cout << "You win."<<endl;
        else if (!chance) cout << "You lose."<<endl;
        else cout << "You chickened out."<<endl;        
    }
    return 0;
}
