C ++：ofstream类将文件保存到哪里？ [英] C++: Where does the ofstream class save the files to?

问题描述

我从Windows移动到Mac，现在我遇到了文件输入/输出类的问题： ifstream & ofstream 。

I moved from Windows to Mac and now I'm experiencing a problem with the file input/output classes: ifstream & ofstream.

在Windows中使用g ++ /代码块运行

In Windows when you run with g++/Code Blocks

ofstream out("output.txt");
out << "TEST";
out.close();

将在同样中创建一个新文件output.txt目录。

A new file "output.txt" will be created in the same directory.

但在MAC OS X中，此文件在我的主目录中创建：/Users/USER_NAME/output.txt

However in MAC OS X, this file is created in my home directory: /Users/USER_NAME/output.txt

如何将此文件与可执行文件一起保存在同一目录中？

How can I have this file in the same directory together with the executable?

PS我使用GCC和CodeBlocks。没有项目 - 我只是编译一个源文件。

P.S. I'm using GCC and CodeBlocks. There are no projects - I'm just compiling a single source file.

UPDATE

我刚刚在XCode中运行相同的代码，它的工作确定！这些文件在项目的Debug目录中创建。

I just ran the same code in XCode, and it works ok! The files are created in project's Debug directory.

所以这不是操作系统的问题。它是Code :: Blocks for Mac。如何在Code :: Blocks中更改工作目录？

So it's not operating system's problem. It's Code::Blocks for Mac. How can I change work directory in Code::Blocks?

推荐答案

流类与所有其他文件打开函数一样，使用当前目录提供相对路径。您可以使用 chdir 的函数来控制当前目录，但更好的解决方案是使用完全限定的文件名。然后删除程序对当前目录的依赖。

The stream classes, like all other file-opening functions, use the current directory when you provide a relative path. You can control the current directory with a function like chdir, but a better solution is to use fully qualified file names. Then you remove your program's dependency on the current directory.
