C++实现从输入中读取字符串

#include<iostream>
#include<string>
using namespace std;
int main(){
  cout << "Please enter a word:\n";
  string s;
  cin>>s;
  cout << "You entered " << s << '\n';
}

#include<iostream>
#include<string>
using namespace std;
int main(){
  cout << "Please enter a line:\n";
  string s;
  getline(cin,s);
  cout << "You entered " << s << '\n';
}
