List files in a directory C++ function.

Implementation of the C++ function that returns a list of files in a certain directory by a given mask (file extension).

// Returns a vector of file name strings in some directory with some extension.
std::vector<std::string> getDirectoryFiles(const fs::path &directory = fs::current_path(),
                                           const std::vector<std::string> extensions = {})

It's my homework task on the subject "Information security".

Usage examples:

Returns the list of the names of all files in the current directory.

auto fileList = getDirectoryFiles();

Returns the list of the names of all files in the current directory with the "*.exe" extension.

auto fileList = getDirectoryFiles(fs::current_path(), {".exe"});

Returns the list of the names of all files in the current directory with the ".png", ".bmp" or ".jpg" extension.

auto fileList = getDirectoryFiles(fs::current_path(), {".png", ".bmp", ".jpg"});
