cin和cin.get()在輸入字元時的區別

 char c(0);

cin>>c;輸入字元時將遺漏輸入中的所有空白字元，而c++換行字元也是一個空白符，因此他同樣也會被遺漏；

cin.get();則總是讀取下一個字元，不會遺漏任何一個；

代碼如下

#include<exception>#include<iostream>using namespace std;int main(){ try {  char c(0);  int count(0);  cout<<"Please type in a line of text.\n";  do{   c = cin.get();   if(!cin)   {    throw exception();   }   if(c == '\n')   {    break;   }   ++count;   cout<<c;  }while(true);     cout<<"\nyou typed in"<<count<<"characters.\n"; } catch(...) {  cerr<<"An exception was thrown"<<"\n"; } return 0;}
