c++ directory listing

To list the contents of a directory in C++, you can use the dirent.h library. Here are the steps to do this:

1. Include the dirent.h header file: cpp #include <dirent.h>

2. Open the directory: cpp DIR *dir; dir = opendir("<directory_path>");

3. Check if the directory was successfully opened: cpp if (dir == NULL) { // handle error }

4. Read the contents of the directory: cpp struct dirent *entry; while ((entry = readdir(dir)) != NULL) { // process each file/folder in the directory // entry->d_name contains the name of the file/folder }

5. Close the directory: cpp closedir(dir);

In the above steps, make sure to replace <directory_path> with the actual path of the directory you want to list. The readdir function is used to read each entry in the directory, and entry->d_name gives the name of the file or folder. You can perform any desired operations on these files or folders within the loop.

Note: The dirent.h library is commonly available on POSIX systems, such as Linux and Unix. If you're working on a different platform, you may need to use a different library or approach for directory listing.
