RT，这是我的 80 分代码：

#include <cstdio>
#include <cstring>
#include <cmath>
#include <iostream>
#include <algorithm>
#define F(i, a, b) for(int (i) = (a); (i) <= (b); ++(i))
#define R(i, a, b) for(int (i) = (a); (i) <= (b); ++(i))
using namespace std;

string attempter;
char s[1007];
int kase = 1;

string getname(char* s) {
	int len = strlen(s);
	string ans = "";
	F(i, 0, len - 1) {
		if(s[i] == ' ' && s[i + 1] == ':') return ans;
		ans += s[i];
	}
}
int getat(char* s) {
	int len = strlen(s), pl = 0, num = 0;
	F(i, 0, len - 1)
		if(s[i] == '@') pl = i, num++;
	if(num != 1) return 0;
	return pl;
}


int main() {
	#ifndef ONLINE_JUDGE
	freopen("P1580.in", "r", stdin);
	freopen("P1580.out", "w", stdout);
	#endif
	while(1) {
		gets(s);
		int len = strlen(s);
		if(len < 2) {
            kase--;
            break;
        }
		string name = getname(s); int plofat = getat(s);
		if(name == attempter) {
			cout << "Successful @" << attempter << " attempt";
            return 0;
		}
		else if(!plofat) {
			cout << "Unsuccessful @" << attempter << " attempt\n";
			printf("%d\n", kase);
			cout << name;
			return 0;
		}
		if(kase == 1) {
			attempter = "yyy loves ";
			F(i, plofat + 11, len - 1) {
				if(s[i] == ' ') break;
				attempter += s[i];

		}
		kase++;
	}
    cout << "Unsuccessful @" << attempter << " attempt\n";
    printf("%d\n", kase);
    cout << "Good Queue Shape";
}

这是我的 60 分代码：

敢问是哪里错了导致我越改分越低？

还有，read ASCII 13 是什么意思？

真·萌新，底下讨论区不要 fAke 谢谢。
