C++ cin.get()有参数时的问题

Question

 int main()
{
    char ch;
    int count = 0;
    cout << "enter char,# quit:" << endl;
    cin.get(ch);
    while (ch!=EOF)
    {
        cout << ch;
        count++;
        cin.get(ch);
    }
    cout << endl<< count <<"done!" << endl;
    cout << EOF<<endl;
    getchar();
}

这个程序，如果输入ctrl+z (Windows环境)，会陷入死循环。。。不明白为什么，请大神指点

Answer 1

cin.get(ch);
->
cin.get(&ch);
