Question

我正在为大学做一个C ++项目。我必须制作历史事件的年表。我有一个类来保存事件，名为“FechaHistorica”，其中set<string>和int为私人成员。该集包含字符串，每个字符串是一个历史事件。 int是所有事件发生的年份。另一个类称为“Cronologia”，其中map<int,FechaHistorica>用于存储每个“FechaHistorica”。

问题在于运营商＆lt;＆lt;我想是FechaHistorica。 executbale使用电影回收两个.txt文件，并且outpout应该是两个文档的并集。这是运营商的代码＆lt;＆lt; os FechaHistorica：

const char SEP = '#';
ostream& operator<< (ostream& os, const FechaHistorica& e) {
    os << e.getYear();

    for(const_iterator p = e.eventos.begin(); p != e.eventos.end(); ++p)
        os << SEP << *p;

    return os;
}

输出结果为：

如您所见，某些年份打印不正确，输出应为：

1900#Sherlock Holmes Baffled#The Enchanted Drawing
1901#Scrooge, or, Marley's Ghost#Star Theatre
1902#A Trip to the Moon

好吧，如果我在每个事件后添加endl，输出都是正确的，我的意思是os << SEP << *p << endl;而不是os << SEP << *p;，但我不希望在每个历史记录后都有endl输出中的事件。我该怎么办？

我希望你能帮助我，谢谢。

包含数据的文件是“movies.txt”和“films.txt” proyect的完整代码在这里：https://github.com/vicase/Practicas-ED/tree/master/Pr%C3%A1ctica%204%20-%20STL%20e%20Iteradores

Answer 1

修正：问题是第一个txt是crlf格式（Windows）而另一个是LF（Ubuntu）。 LF中的两个文件都可以正常工作。谢谢大家

（C ++）重载运算符＆lt;＆lt; ，如果我不使用endl
