（C++）每次读取一个用户输入的单词，并分别指出以元音打头和以辅音打头以及不属于这两类的单词数量。

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

int main()
{
unsigned int vowel = 0;
unsigned int consonant = 0;
unsigned int other = 0;
string ch;

cout << "请输入（退出请输入q）：" << endl;

while ((cin>>ch))
{
//如果用户输入q，循环终止
	if (ch.length() == 1 && ch[0] == 'q')
	{
		break;
	}
//判断输入单词的首字母
	if (isalpha(ch[0]))
	{
		if (ch[0] == 'a' || ch[0] == 'e' || ch[0] == 'i' || ch[0] == 'u' || ch[0] == 'o')
		{
			vowel++;
		}
		else
		{
			consonant++;
		}
	}
	else
	{
		other++;
	}
}
cout << "有"<<vowel <<"个元音打头的单词"<< endl;
cout << "有"<<consonant<<"个辅音打头的单词" << endl;
cout << other <<"个单词不属于这两类"<< endl;
system("pause");
	return 0;
