Cin＆gt;＆gt;阅读输入

Question

当我输入＆＃34; M12 9UB＆＃34;这段代码：

std::string postal_code;

cout << "Enter postal code: ";
cin >> postal_code;
cout << "Your postal code is: " << postal_code << endl;

输出为＆＃34;您的邮政编码为：M12＆＃34;。

那么如何让cin读取整行？

Answer 1

使用std::getline从流中读取整行：

std::getline(std::cin, postal_code);

Live example.

Answer 2

您可以像这样使用C ++ getline函数：

#include <iostream>
using namespace std;

int main()
{
    std::string postal_code;

    cout << "Enter postal code: ";
    getline(cin,postal_code);
    cout << "Your postal code is: " << postal_code << endl;
}
