テキストファイルから特定の要素を読み取るにはどうすればよいですか？

Question

私は、書籍情報（タイトル、著者など）の複数のセットを持つテキストファイルを持っています。私は、ファイルから読み込み、各情報を対応する文字列に割り当てるためにループを使用できる必要があります。私はファイル全体を見渡す場所に作業をしていますが、ファイルを調べているうちにうんざりしています。

Gone With the Wind, Margaret Mitchell, Hardcover, 1936, 17.49 
The Adventures of Sherlock Holmes, Arthur Doyle, Paperback, 1892, 6.85 
The Illustrated A Brief History of Time, Stephen Hawking, Hardcover, 1996, 9.59 
Frankenstein, Mary Shelley, Paperback, 1818, 7.99 
Command Authority, Tom Clancy, Paperback, 2013, 15.99 
Origin, Dan Brown, Ebook, 2017, 14.99 
The Lost Order, Steve Berry, Audiobook, 2017, 5.95 
The Hunt for Red October, Tom Clacy, Audiobook, 1984, 7.00 
Patriot Games, Tom Clancy, Audiobook, 1987, 22.50 
The 14th Colony, Steve Berry, Paperback, 2016, 9.99 
The Bishop's Pawn, Steve Berry, Ebook, 2018, 14.99 
Pride and Prejudice, Jane Austen, Ebook, 1813, 8.99 
Sense and Sensibility, Jane Austen, Hardcover, 1811, 19.99 
Wuthering Heights, Emily Bronte, Paperback, 1847, 6.99 
Jane Eyre, Charlotte Bronte, Hardcover, 1847, 10.95 
Anna Karenina, Leo Tolstoy, Paperback, 1877, 5.99 
Sahara, Clive Cussler, Ebook, 1992, 5.99 
The Notebook, Nicholas Sparks, Hardcover, 1996, 12.59 
A Walk to Remember, Nicholas Sparks, Ebook, 1999, 7.99 
See Me, Nicholas Sparks, Ebook, 2015, 7.99 
The Last Song, Nicholas Sparks, Paperback, 2009, 5.99 
The Wedding, Nicholas Sparks, Ebook, 2003, 7.99 

私の思考は、それは、コンマまで読んで文字列に情報のその部分を割り当て、その後、継続するということでした。ここで

Book readOne(ifstream &fin) { 
string titleOne; 
getline(fin, titleOne, ','); 
string firstOne; 
getline(fin, firstOne, ','); 
string lastOne; 
getline(fin, lastOne, ','); 
string formatOne; 
getline(fin, formatOne, ','); 
string pubDateOne; 
getline(fin, pubDateOne, ','); 
string priceOne; 
getline(fin, priceOne); 

はテキストファイルです。代わりに、特定のコンマが表示されないかのように出力されます。

これはcsv（カンマ区切り値）ファイルに過ぎません。そしてそれを読むための十分なコードサンプルがあります。 this sampleを参照してください。
