How to getline when you have used cin >> char?

[weihui qiu <weihuiq at yahoo dot com>]

Hi,

There is a strange behavior about g++ compiler under
unix system. When I first cin >> char and then
cin.getline(char*, int), it don't wait for me to input
a line, but directly execute the next line. How to
solve this problem? Please help me!!

Regards!
Weihui

int main () {
    char c;
    cout << "Input a char!!";
    cin >> c;
    cout << c << endl;
    char* line = new char[1000];
    cout << "Please input sentence: " << endl;
    cin.getline(line, 1000);
    cout << line << endl;
    cout << "Input a char!!";
    cin >> c;
    cout << c << endl;
    return 0;
}
