如何在 C++ 中更改文本文件的名称? [英] How to change a text file's name in C++?

问题描述

我想更改 txt 文件的名称，但我找不到如何执行此操作.

I would like to change a txt file's name, but I can not find how to do this.

例如，我想在我的 C++ 程序中将 foo.txt 重命名为 boo.txt.

For example, I want to rename foo.txt to boo.txt in my C++ program.

推荐答案

#include (或 )并使用 重命名(或std::rename):

#include <stdio.h> (or <cstdio>) and use rename (or std::rename):

rename("oldname.txt", "newname.txt");

与流行的看法相反，它包含在标准库中，并且在一定程度上是可移植的——当然，字符串的允许内容会因目标系统而异.

Contrary to popular belief, this is included in the standard library, and is portable up to a point -- though of course the allowable contents of the strings will vary with the target system.
