Write a C program myls$2$ whose behavior resembles that of the system command $1$ s$.$ myls $2$ must print

the names of files in the current directory in columns of equal width. my $1.s2$ must accept the following

parameters:

$ myls$2[-$ars$][$directory$]$

Overall behavior of my $1s2$ is identical to that of myls $1$ described in lab$5.$

myl$.$s$2$ needs to present its output using multiple columns of the same width as shown below:

Use the hint on p$.164($Molay textbook$)$ to determine the width of the current terminal window.

Test my$1$s$2$ using the files with names of varying length archived in this ZIP file. Use the following test

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

Run each of the test cases above twice:

in a relatively wide terminal window resulting in at least two rows of file names, and

in a relatively narrow terminal window resulting in at least four rows of file names.
