Need a C++ program of a General Tree Project. This program should do the following:

- Read your directory tree (atleast depth 2) and insert into your general tree data structure.

- Calculate the size of the directory.

(Note the code should be able to take the root directory path as user input or as a string variable declared in the main function. It should parse the directory to atleast a depth of 2 from the given starting point)

Please have comments on the program so I know what is going on. Please let me know if you need anything else.

Thanks!
