path& replace_extension( const path& replacement = path() ); (1) (since C++17) 将扩展替换为replacement的默认值时移除replacement被使用了。 首先,如果这条路径有一个extension(),它被移除了。 然后,如果replacement不是空的,也不是以点字符开头的。

The root path isc:/. The relative path isabc/xyz/def.ext. The parent path isc:/abc/xyz. The filename isdef.ext. The stem isdef. The extension is.ext. A minor difference is the preferred separator between the sequence of directories in a pathname. Both operating systems let you write ...
