need help with this last program. Best answer to whoever answers it correctly! Can extend time for you if needed just comment and notify me! ALSO if you can do the extra credit that will be very much appreciated!

Simple TCP File Server

Purpose

Exercise TCP server socket system calls.

Assignment

Write a C++ program that implements a simple file server.

Program

Implement a C++ program that in a loop listens on a port for incoming TCP requests from clients. For each accepted
incoming request it forks a child to read and process the request. The parent process continues to listen and accept
incoming TCP requests in an endless loop.
The program accepts 2 command line parameters:
1. the port number to listen on,
2. the pathname to a directory that serves as root to all requested files or directories.

For example:

% ./z123456 9001 www
The requests received by the program are of the form:
GET pathname
where the pathname refers to a file or directory to be sent back to the client. The file/directory will be found in the
directory specified on the command line. The following rules apply to the pathname:
it must start with a "/"
it may contain additional "/" path separators to access subdirectories
a single "/" character refers to the directory specified on the command line
a trailing "/" in the pathname can be ignored if the pathname refers to a directory
any data in the request beyond the pathname should be ignored
it may not contain the substring ".."
If the pathname refers to a file, then the content of the file is returned to the client.
If the pathname refers to a directory, then:
if a file "index.html" exists in that directory, it will be returned;
else, a list of files in that directory will be returned (not including any file that starts with ".").

Error Checking

If the command line arguments are incomplete, or if the path to the root directory is invalid, print an error message and exit. If any of the system calls fail, the program should use "perror" to report and exit. If the pathname in the GET request is invalid or a file/directory cannot be accessed, then an appropriate error message should be contructed and sent back to 1 of 2 the client.

Other Points

You can test your server program with the TCP echo client that was shown in class
Make sure that your assignment is contained in a single file called "z123456.cxx" based on your Z-id;
Make sure that your program compiles, links and runs fine on your Linux system, turing or hopper.


Extra Credit
If you implement this part of the assignment, please indicate it in the file header comment.
implement a second request command:
INFO
It will return the current time and date in text format to the client.
