There are many words in the file, read them out and store them in the linked list, brothers and sisters, what should I do, give a specific answer that can be run without errors, thank you brother! !! !!

getline () reads a line into str, separating each word
Then list :: push_back ()

Can you elaborate on it, a younger rookie.

#include <iostream>

using namespace std;
bool is_word (word) {
// Judge the word or not is up to you, if it is rough
return true;
};
int main () {
cout << "Please enter a file name:";
string fname;
cin >> fname;
ifstream in (fname);
string word;
list <string> ls;
while (in >> word) {
if (is_word (word)) {
  ls.push_back (word);
} // endif
} // endwhile
cout << "Word list:\n";
copy (ls.begin (), ls.end (), ostream_iterator <string> (cout, "\n"));
}
