题目描述

给定当前的时间，请用英文的读法将它读出来。
时间用时h和分m表示，在英文的读法中，读一个时间的方法是：
如果m为0，则将时读出来，然后加上“o'clock”，如3:00读作“three  o'clock”。
如果m不为0，则将时读出来，然后将分读出来，如5:30读作“five  thirty”。
时和分的读法使用的是英文数字的读法，其中0~20读作：
0:zero,  1:  one,  2:two,  3:three,  4:four,  5:five,  6:six,  7:seven,  8:eight,  9:nine,  10:ten,  11:eleven,  12:twelve,  13:thirteen,  14:fourteen,  15:fifteen,  16:sixteen,  17:seventeen,  18:eighteen,  19:nineteen,  20:twenty。
30读作thirty，40读作forty，50读作fifty。
对于大于20小于60的数字，首先读整十的数，然后再加上个位数。如31首先读30再加1的读法，读作“thirty  one”。
按上面的规则21:54读作“twenty  one  fifty  four”，9:07读作“nine  seven”，0:15读作“zero  fifteen”。

输入

输入包含两个非负整数h和m，表示时间的时和分。非零的数字前没有前导0。h小于24，m小于60。 

输出

输出时间时刻的英文。

样例输入

0 15 

样例输出

zero fifteen

解题思路：

1：对m只能用0~23的英文表示

2：对n 可以先判断n的值，在对其循环

3：都用switch循环

#include<iostream>
#include<cmath>
using namespace std;
int main()
{
	int m,n;
	cin>>m>>n;
	switch(m)
