此函数可读取整行,包括前导和嵌入的空格,并将其存储在字符串对象中。
getline 函数如下所示:
getline(cin, inputLine);
其中 cin 是正在读取的输入流,而 inputLine 是接收输入字符串的 string 变量的名称。下面的程序演示了 getline 函数的应用:
// This program illustrates using the getline function
//to read character data into a string object.
#include <iostream>
#include <string> // Header file needed to use string objects
using namespace std;
int main()
{
string name;
string city;
cout << "Please enter your name: ";
getline(cin, name);
cout << "Enter the city you live in: ";
getline(cin, city);
cout << "Hello, " << name << endl;
cout << "You live in " << city << endl;
return ;
}
