c++ - 如何阅读单词而不是字符？

Question

我目前正在尝试从 .txt 文档中读取一堆单词，但只能设法读取字符并显示它们。我想做同样的事情，但要用完整的单词。

我的代码:

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

int main()
{

ifstream infile("banned.txt");
if (!infile)

{

    cout << "ERROR: ";
    cout << "Can't open input file\n";

 }

 infile >> noskipws;
 while (!infile.eof())
 {
    char ch;
    infile >> ch;

    // Useful to check that the read isn't the end of file
    // - this stops an extra character being output at the end of the loop
    if (!infile.eof())
    {
        cout << ch << endl;
    }
 }
system("pause");
}

将 char ch; 更改为 std::string word; 并将 infile >> ch; 更改为 infile >> word; 就大功告成了。或者更好的做法是像这样循环:

std::string word;
while (infile >> word)
{
    cout << word << endl;
}
