我对stoi（）有一个奇怪的问题。继承我的代码：
ifstream bookStream("inventory.txt", ios::in);
book tempBook;
string tmp;
if (bookStream.is_open())
while (!bookStream.eof()) {
getline(bookStream, tmp, '#');
//cout << tmp << endl;
tempBook.bookId = stoi(tmp);
getline(bookStream, tempBook.title, '#');
tempBook.title = tmp;
getline(bookStream, tempBook.author, '#');
tempBook.author = tmp;
getline(bookStream, tmp, '#');
tempBook.cost = stof(tmp);
getline(bookStream, tmp, '#');
tempBook.price = stof(tmp);
getline(bookStream, tmp, '#');
tempBook.quantity = stoi(tmp);
}
else
cout << "error opening file" << endl;
我收到运行时错误（已调用abort）。如果我评论代码的下半部分并运行：
getline(bookStream, tmp, '#');
cout << tmp << endl;
在while循环中，它将打印出每个字符串应该如何，每行都有整数和字符串，没有“＃”。即使我评论了除第一个stoi（）之外的一切，它也会抛出相同的错误。
以下是我的inventory.txt中的几行：
116807#A Tale of Two Cities#Charles Dickens#3.73#9.99#1
111272#The Iliad#Homer#2.78#9.99#10
164440#The Great Gatsby#F. Scott Fitzgerald#4.92#9.99#8
cout << tmp << endl;
