Iterating Recursively Through Files and Directories in Standard C

To traverse every file and directory recursively within a specified path in standard C , a range-based for loop can be employed in conjunction with the header, which was introduced in C 17.

C 17 and Above:

In C 17 and subsequent versions, the following code snippet can be used for recursive iteration:

#include <filesystem>

using recursive_directory_iterator = std::filesystem::recursive_directory_iterator;

for (const auto& dirEntry : recursive_directory_iterator(myPath)) {
  std::cout << dirEntry << std::endl;
}

This code will output all files and directories within myPath and its subdirectories.

It's important to note that std::filesystem is an integral part of the C standard library from C 17 onwards, and can be accessed through the header.
