[edit] Example
Run this code
#include <filesystem> #include <iostream> namespace fs = std::filesystem; int main() { fs::path p = fs::current_path(); std::cout << "The current path " << p << " decomposes into:\n" << "root name " << p.root_name() << '\n' << "root directory " << p.root_directory() << '\n' << "relative path " << p.relative_path() << '\n'; }
Possible output:
The current path "C:\Users\abcdef\Local Settings\temp" decomposes into: root name "C:" root directory "\" relative path "Users\abcdef\Local Settings\temp"
