CS 355 - Systems Programming Lab 3 - implementing who

Objective: write a program that can display the list of users currently logged in to the Unix computer.

What to do?

Extend the code presented in class that simulates and prints user login records so that the information about the user's terminal is also stored in the file and then printed. Your program output should look like this:
```
user_0 last logged in on terminal_10 on Mon Jun 3 13:10:53 2024
user_1 last logged in on terminal_11 on Mon Jun 3 13:10:54 2024
user_2 last logged in on terminal_12 on Mon Jun 3 13:10:55 2024
```
You are not allowed to use any file IO functions other than the system calls discussed in class.

What to submit?

A single C source code file with your work.
One screenshot (in PNG or JPG format) showing the results of executing your program.
