问题描述

这只是一个简单的问题。但我试图输出数据到一个文件，这很好。
然而，我还试图在适当的点实现一个新行，所以数据，打印在单独的行。

This is just a quick question. But I am trying to output data to a file, which works fine.However I am also trying to implement a new line at the appropriate point so the data, prints on individual lines.

这是我的代码当前的样子：

This is how my code currently looks:

main.cpp

Writer w("Output.txt");
    w.writeString("The number of words in the script are: ");
    w.writeInt(count);
    w.writeEol();
    w.writeString("The number of Officers in the script are: ");
    w.writeInt(ofCount);
    w.writeEol();
    w.writeString("The number of Courtiers in the script are: ");
    w.writeInt(cCount);
        w.close();

Writer.cpp

void Writer::writeEol()
{
    out << "\n" << endl;
}

我的代码必须以这种方式实现，因为我的整个系统是围绕它像这样。

My code has to be implemented this way as my whole system is built around it like this.

所以我的问题是，我如何调整我的Writer :: writeEol（）以添加一个新行到我的输出文件？

So my question is, how would I adjust my Writer::writeEol() to add a new line to my output file?

我的输出文件目前是这样的：

My output file currently comes out like this:

    The number of words in the script are: 32339The number of Officers in the script are: 2The number of Courtiers in the script are: 9

帮助非常感谢。：）

推荐答案

没有正确的问题，我可以猜测你想学什么，所以随时更新你的问题与一个实际的问题：

Without a proper question I can just guess what you're trying to learn, so feel free to update your "question" with an actual question:

你本质上是写两个换行符到文件，这取决于编码（即Windows或Unix换行符），你不会看到区别：

You're essentially writing two line breaks into the file, depending on the encoding (i.e. Windows or Unix line breaks) you won't see the difference:

std :: endl 会自动包含正确的字符来创建换行符。也不需要写\\\。

std::endl will automatically include the correct character to create a linebreak. There's no need to write "\n" as well.

code> std :: endl ，除非你真的想在特定位置换行：

Also you don't have to pass std::endl to the stream unless you really want a line break at the specific position:

std::cout << "The result is: ";
std::cout << 50 << std::endl;

请记住，根据您的编辑器，您可能不会看到所有换行符。 Windows记事本不会只用\\\显示换行符。它将改为显示为不可见字符。对于接受的实际换行符，您将得到\r\\\。相比之下，开源编辑器Notepad ++接受并显示两种换行符。

Keep in mind that depending on your editor you might not see all line breaks, e.g. Windows Notepad won't show a line break with only \n. It will instead appear as an invisible character. For actual line breaks that are accepted you'd beed \r\n. In comparison, the Open Source editor Notepad++ accepts and displays both kinds of line breaks.
