How come my input file stream isn't detecting the new lines I am looking for?

My question is simple, but I can't seem to find the answer anywhere. I am checking for \n char's in my program as I read in characters, but my program does not seem to detect them. As can be seen, I stay in the while loop even though there is the condition (input != \'n'). This is even though my input file has plenty of new lines. As a result, the whole string gets interpreted as one word.

ifstream d_file;
char input = '\0';
string word;


d_file.open(dict_file);
d_file >> input;
//declares string for characters to be put into
while ( !d_file.eof())
{
    //reinitializes the word
    word = "";
    while (input != '\n' && !d_file.eof())
    {
        cout << "\n";
        putchar (tolower(input));
        //appends the string with characters
        word+=input;
        d_file >> input;
    }   
    dictionary.insert(word);
    d_file >> input;
    cout << word << "   ";
}


d_file.close();

as can maybe be seen, I don't want all one word together and then a space. I want word separated by spaces at the end.
