cin.get()和cin.getline()之间的区别

cin.getline()和cin.get()都是对输入的面向行的读取,即一次读取整行而不是单个数字或字符,但是二者有一定的区别。

cin.get()每次读取一整行并把由Enter键生成的换行符留在输入队列中，然而cin.getline()每次读取一整行并把由Enter键生成的换行符抛弃,比如：

#include <iostream>
using std::cin;
using std::cout;
const int SIZE = 15;
int main( ){
    cout << "Enter your name:";
    char name[SIZE];
    cin.getline(name,SIZE);
    cout << "name:" << name;
    cout << "\nEnter your address:";
    char address[SIZE];
    cin.get(address,SIZE);
    cout << "address:" << address;
}

输出:
Enter your name:zy
name:zy
Enter your address:njfu
address:njfu
