c++11 - c++输入字符的问题

Question

我是想输入一句话进去，英文的。这样就需要保存住单词之间的空格，所以就是保存字符。我这个代码编译的时候没有错误,但是运行时，我输入一句话之后按回车，并不会输出我刚输入的内容。没有反应。请大家看一下。谢谢。

#include <iostream>
#include <string>
#include <vector>
using namespace std;

int main()
{
    vector<char> ch;
    char word;
    int i;
    cout << "enter a sentence:" << endl;
    while (cin >> word)
    {
        ch.push_back(word);
    }
    for(auto c : ch)
        cout << c <<endl;
    system("pause");
    return 0;
}

Answer 1

The poster wants to find out

while (cin >> word)

The end condition of

is not that you enter the "newline character", but the "end of file character" (EOF), which is ctrl+D on Linux and ctrl+Z on Windows. Therefore, your program cannot input one line and output one line. Everything you input is successful, but it is saved in word and no output statement is executed.
