cin.get()和cin.getline()之間的區別

cin.getline()和cin.get()都是對輸入的面向行的讀取,即一次讀取整行而不是單個數字或字符,但是二者有一定的區別。

cin.get()每次讀取一整行並把由Enter鍵生成的換行符留在輸入隊列中，然而cin.getline()每次讀取一整行並把由Enter鍵生成的換行符拋棄,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;
}

輸出:
Enter your name:zy
name:zy
Enter your address:njfu
address:njfu
