Please write a C code with online gdb$.$com, that can run with the following zipped file is$\_$test$\_$files.Please show proof of output and explain how to run the code with the uploaded file to get the output!

What to do$?$

Write a C program myls $1$ whose behavior resembles that of the system command $1s.$ myls $1$ must

accept the following parameters:

$ myls$1[-$ars$][$directory$]$

If myls$1$ is provided with no parameters, it lists the names of all files in the current directory, one file

name per line.

directory specifies the name of a directory, in which case myls$1$ lists the names of files within that

directory.

$-$a switch forces myls $1$ to display the names of hidden files $($whose names start with a $".").$ In the

absence of this switch, hidden files are not listed.

$-s$ switch sorts the filenames in the lexicographical order.

$-r$ switch sorts the filenames in the reverse lexicographical order.

You must use system calls opendir$(),$ readdir$(),$ and closedir$().$

Hint: consider using an array of strings to store the list of file names and then sorting it using qsort $().$

Test my$1.$s$1$ using the files archived in this ZIP file, which contains several nested directories $($named

dirA,dirB, and dirA$1,$ each with a number of short text files $($named file$*.$txt$).$ Use the following

test cases when running myls$1$ from the directory at the same level with dirA and dirB:

What to submit?

A single C source code file with your work.

Several screenshots $($in PNG or JPG format$)$ showing the results of executing the test cases listed above

on a Linux terminal.
