如何在写入文件时放置换行符 [英] How Can I place a Line Break while writing to a file

问题描述

我正在创建一个配置文件，点击下面的代码按钮。
$ b

  fputs（AutoStart =+ strAutoWinStart + 
AutLogHistory =+ strAutoLogSvrHistory + 
AutoScan =+ strAutoScanDetect + 
AutoMount =+ strAutoMount + 
AutoOpen =+ strAutoOpenWin + 
LastConnectedSvr =+ strAutoDetLastConSvr，pFile）; 
  

和输出文件如下所示：

< blockquote>

AutoStart = 1AutLogHistory = 0AutoScan = 1AutoMount = 0AutoOpen = 1LastConnectedSvr = 0

相反，我需要输出在每个参数中应该有一个换行符，如下所示：

AutoStart = 1

AutLogHistory = 0 >
AutoScan = 1

AutoMount = 0

AutoOpen = 1

LastConnectedSvr = 0

解决方案

在UNIX样式的换行符中添加\r\\\
（或\\\
）以在文件。

Windows上的某些编辑器（如记事本）不能很好地处理UNIX样式的换行符，只显示一行内容。为了实现跨操作系统的最大可移植性，请使用\ n。为了在Windows中的最大可用性，使用\r\\\
。

更好：使用std :: ofstream和std :: endl - 你的问题被标记C ++毕竟。

I am creating a configuration file on click of a button by the following code.

fputs(  "AutoStart = " +strAutoWinStart + 
        "AutLogHistory = " +strAutoLogSvrHistory + 
        "AutoScan= " +strAutoScanDetect + 
        "AutoMount = "+ strAutoMount + 
        "AutoOpen = "+ strAutoOpenWin + 
        "LastConnectedSvr = "+ strAutoDetLastConSvr,pFile);

and the Output file looks as below:

AutoStart = 1AutLogHistory = 0AutoScan= 1AutoMount = 0AutoOpen = 1LastConnectedSvr = 0

Instead I need my output should have a line break in each parameter and look as below:

AutoStart = 1
AutLogHistory = 0
AutoScan= 1
AutoMount = 0
AutoOpen = 1
LastConnectedSvr = 0

解决方案

Add "\r\n" (or "\n" for UNIX-style linefeeds) to create a new line in the file.

Some editors on Windows such as Notepad don't handle UNIX-style linefeeds well, showing everything on one line. For the most portability across operating systems, use "\n". For the most usability in Windows, use "\r\n".

Even better: use std::ofstream with std::endl - your question is tagged C++ after all.
