C++에서 문자를 입력 받기 위해
string strId;
cin >> strId;
명령을 사용하면 띄어쓰기로 구분된 문장을 입력 받지 못한다.(아래 예시)
#include <iostream>
#include <string>
using namespace std;
int main ()
{
string strId;
cout << "ID를 입력 해주세요. " << endl;
cin >> strId;
cout << "Hello " << strId << "!" << endl;
return 0;
}
아래와 같이 getline(cin, strId);
와 같이 getline을 사용하여 문장을 입력 받는다.
#include <iostream>
#include <string>
using namespace std;
int main ()
{
string strId;
cout << "ID를 입력 해주세요. " << endl;
getline (cin, strId);
cout << "Hello " << strId << "!" << endl;
return 0;
}
