这个题样例过了，实际WA了

#include <iostream>
#include <cstdio>
#include <string>
using namespace std;

bool pd(const char &c)
{
	return (c == 'a' || c == 'A' || c == 'e' || c == 'E' || c == 'i' || c == 'I' || c == 'o' || c == 'O' || c == 'u' || c == 'U');
}
int main()
{
	string s;
	while(cin >> s)
	{
		bool f = false;
		int len = s.length() - 1;
		if(s[len] == '.') f = true;
		if(pd(s[0]))
		{
			if(f)
			{
				for(int i = 0; i <= len - 1; i++)
				{
					cout << s[i];
				}
				cout << "ay.";
			}
			else
			{
				cout << s << "ay";
			}
		}
		else
		{
			for(int i = 1; i <= len; i++)
			{
				cout << s[i];
			}
			cout << s[0] << "ay";
			if(f)
			{
				cout << ".";
			}
		}
		char b = getchar();
		cout << b;
	}
	return 0;
}
