问题描述

我想重命名文件，但是我正在获取文件，但是很难重命名它.这是我的代码.

I want to rename a file and I am getting the file, but having a hard time renaming it. Here is my code.

rename(string("c:\\Users\\DS\\Downloads\\").append(string(iter->cFileName)).c_str()myfile.txt);

推荐答案

所有人都告诉我们您的问题是什么，请不要让我们来解决.

您缺少在myfile.txt之前缺少逗号(,)的情况，并且需要将myfile.txt括在双撇号(")

First of all tell us what your problem is, do not leave it to us to figure out.

You''re missing a missing a comma (,) before myfile.txt and you need to enclose myfile.txt in double apostrophes (")

中编译.必须为int rename ( const char * oldname, const char * newname );， http://www.cplusplus.com/reference/clibrary/cstdio/rename/ [ ^ ].分别计算两个文件名，然后传递给函数.

It won''t compile. Must be int rename ( const char * oldname, const char * newname );, http://www.cplusplus.com/reference/clibrary/cstdio/rename/[^]. Calculate two file names separately and pass to the function.
