How do you iterate through every file/directory recursively in standard C++?

by

From C++17 onward, the <filesystem> header, and range-for, you can simply do this:

#include <filesystem>

using recursive_directory_iterator = std::filesystem::recursive_directory_iterator;
...
for (const auto& dirEntry : recursive_directory_iterator(myPath))
     std::cout << dirEntry << std::endl;

As of C++17, std::filesystem is part of the standard library and can be found in the <filesystem> header (no longer “experimental”).
