c++ - Cross Platform Way to make a directory including subfolders?

Question

Is there a way using the standard c or c++ library to make a directory, including the subfolders that may be required given a string of the absolute path?

Thanks

Yes, In C++17, You can use filesystem

#if __cplusplus < 201703L // If the version of C++ is less than 17
#include <experimental/filesystem>
    // It was still in the experimental:: namespace
    namespace fs = std::experimental::filesystem;
#else
#include <filesystem>
    namespace fs = std::filesystem;
#endif

int main()
{
    // create multiple directories/sub-directories.
    fs::create_directories("SO/1/2/a"); 
    // create only one directory.
    fs::create_directory("SO/1/2/b");
    // remove the directory "SO/1/2/a".
    fs::remove("SO/1/2/a");
    // remove "SO/2" with all its sub-directories.
    fs::remove_all("SO/2");
}

Note to use only forward slashes / and you may need to include <experimental/filesystem>.
