What to do$?$

Write a C program mycat whose behavior resembles that of the system command cat. Unlike the

standard cat, mycat will not work with the standard input. mycat must accept the following

parameters:

mycat must receive at least one parameter, file$1,$ whose content will be printed on the screen. If more

than one file name is specified, the contents of all of the files will be printed.

mycat must accept any combination of the following switches:

$-$b Number the non$-$blank output lines, starting at $1.$

$-$e Display a dollar sign $(\text{'}$ $ $\text{'})$ at the end of each line.

$-$n Number the output lines, starting at $1.$

$-$s Squeeze $($remove$)$ all empty lines, causing the output to be single spaced. An empty line can

contain one or more whitespace characters $($e$.$g$.$ space, tab, newline, carriage return$).$

You may not use fopen $()$ and fgets $()$ to read the data from input files.

Line numbering must not be restarted at the beginning f every file.

When both $-b$ and $-n$ are specified, only line number should be printed.

Test mycat using the following text files: file$1.$txt$,$ file$2.$txt$,$ and file$3.$txt$.$ Use the following test cases:
