cin空格结束 getline可输入空格

#include 
#include  // Header file needed to use string objects
using namespace std;

int main()
{
    string name;
    string city;
    cout << "Please enter your name: ";
    //cin >> name;//这里输入aa bb只会识别aa空格为结束
	getline(cin,name);//可以识别到空格
    cout << "Enter the city you live in: ";
    cin >> city;
    cout << "Hello, " << name << endl;
    cout << "You live in " << city << endl;
    return 0;
}

getline    是从键盘输入一个以ENTER键标志结束的字符串

与 getline 一样，cin.getline 允许读取包含空格的字符串

	cin.getline(a, 6);// 此处输入12345(enter)
	cout << a << endl;

最多可以读取5个字符，少一个
