HDU 1039 - Easier Done Than Said?

字符串水题，只要条件判全就能过。

代码如下：

#include<iostream>
#include<cstdio>
#include<cstring>
#include<cstdlib>
#include<cmath>

using namespace std;

bool Judge_Vowel(char ch)
{
    if(ch=='a'|| ch=='e' || ch=='i' ||
       ch=='o' || ch=='u')
        return true;
    return false;
}
int main()
{
#ifdef test
    freopen("sample.txt", "r", stdin);
#endif
    char str[25];
    while(scanf("%s", str))
    {
        if(!strcmp(str, "end"))
            break;
        bool flag_1=false, flag_2=true;
        int len = strlen(str);
        for(int i=0; i<len; i++)
        {
            if(Judge_Vowel(str[i]))
                flag_1 = true;
            if(i>=2 && Judge_Vowel(str[i-2])
               && Judge_Vowel(str[i-1])
               && Judge_Vowel(str[i]))
            {
                flag_2 = false;
                    break;
            }
            else if(i>=2 && !Judge_Vowel(str[i-2])
               && !Judge_Vowel(str[i-1])
               && !Judge_Vowel(str[i]))
            {
                flag_2 = false;
                    break;
            }
            if(i>0 && str[i]==str[i-1] && str[i]!='e' && str[i]!='o')
            {
                flag_2 = false;
                    break;
            }
        }
        if(flag_1 && flag_2)
            printf("<%s> is acceptable.\n", str);
        else
            printf("<%s> is not acceptable.\n", str);
    }
    return 0;
}
