Reproduce the same behavior of the Unix command 'cat'

Under the project root directory, there is a Makefile, once launched it will build the entire project for you and generate an executable binary named ft_cat

./ft_cat [OPTION]... [FILE]...

Concatenate FILE(s) to standard output.

With no FILE, or when FILE is -, read standard input.

-A, --show-all equivalent to -vET

-b, --number-nonblank number nonempty output lines, overrides -n

-e equivalent to -vE

-E, --show-ends display $ at end of each line

-n, --number number all output lines

-s, --squeeze-blank suppress repeated empty output lines

-t equivalent to -vT

-T, --show-tabs display TAB characters as ^I

-v, --show-nonprinting use ^ and M- notation, except for LFD and TAB.

--help display this help and exit

--version output version information and exit

  $> ./ft_cat f - g

Output f's content, then standard input, then g's content.

$> ./ft_cat 

Copy standard input to standard output.
