1. **创建新文件**:使用`std::ofstream`打开一个新的文件,同样设置为二进制模式。 2. **写入数据**:将二进制数据流中的内容写入新文件。 3. **关闭文件**:完成写入后,关闭新文件。 以下是对应的代码片段: ``... 复制文件 std::ofstream destination("目标文件路径", std::ios::binary); if (!so...

new_filename-指向空终止字符串的指针,字符串含有文件的新路径 返回值 成功时为0,错误时为非零值。 注解 POSIX规定此函数语义上的许多额外细节,它们由std::filesystem::rename复制到 C++ 中。 示例 运行此代码 #include <iostream>#include <fstream>#include <cstdio>intmain(){boolok{std::ofstream(...
