Description : This is Question #2: Implementation of a double linked list.
Each node is a struct, which consists of an array in the size of 10, a counter (which
holds the number of the last populated cell) and two pointers: previous node and next node.
main:
Main has two pointers: head and tail of the list. Both are null at the beginning.
addToList:
Receives a reference to the head of the list, tails of the list and the new character.
When adding a new char to the array:
- Check if the list is empty
- If so, create a new node, add the char into the chars array, make head and tail
pointers to point to the new node
- Otherwise, check the tail's counter. if there's free space in the array,
add the char.
- Otherwise, create a new node, insert the char into index 0, make the tail->
to point to the new node, the new node->prev to point to the tail, and then
make the new node as the new tail
printList:
Receives the head of the list (a copy).
Prints the whole array char by char. Once done, we do the same for the next node.
Function stops printing when head becomes NULL.
freeList:
Receives a pointer to first node in the list.
A temporary pointer points to the head of the list.
The head pointer then points to the next in the link, so we can safely free the first
node in the list, which the temp pointer is pointing to.
Doing the same for each node until head points to NULL and then we know that the list is empty.

/// assembler. It does however preclude the merge of the host compile and
/// backend phases. There are also two offloading specific options:
/// -fopenmp-is-device: will tell the frontend that it will generate code for a
/// target.
/// -fopenmp-host-ir-file-path: specifies the host IR file that can be loaded by
/// the target code generation to gather information about which declaration

If the caller did not specify anything,
the default is REQUIRE_ORDER if the environment variable

REQUIRE_ORDER means don't recognize them as options;
stop option processing when the first non-option is seen.
This is what Unix does.
This mode of operation is selected by either setting the environment
variable POSIXLY_CORRECT, or using `+' as the first character
of the list of option characters.
PERMUTE is the default. We permute the contents of ARGV as we scan,
so that eventually all the non-options are at the end. This allows options
to be given in any order, even with programs that were not written to
expect this.
RETURN_IN_ORDER is an option available to programs that were written
to expect options and other ARGV-elements in any order and that care about
the ordering of the two. We describe each non-option ARGV-element
as if it were the argument of an option with character code 1.
Using `-' as the first character of the list of option characters
selects this mode of operation.
The special argument `--' forces an end of option-scanning regardless
of the value of `ordering'. In the case of RETURN_IN_ORDER, only
`--' can cause `getopt' to return -1 with `optind' != ARGC. */

/* Scan elements of ARGV (whose length is ARGC) for option characters
given in OPTSTRING.
If an element of ARGV starts with '-', and is not exactly "-" or "--",
then it is an option element. The characters of this element
(aside from the initial '-') are option characters. If `getopt'
is called repeatedly, it returns successively each of the option characters
from each of the option elements.
If `getopt' finds another option character, it returns that character,
updating `optind' and `nextchar' so that the next call to `getopt' can
resume the scan with the following option character or ARGV-element.
If there are no more option characters, `getopt' returns -1.
Then `optind' is the index in ARGV of the first ARGV-element
that is not an option. (The ARGV-elements have been permuted
so that those that are not options now come last.)
OPTSTRING is a string containing the legitimate option characters.
If an option character is seen that is not listed in OPTSTRING,
return '?' after printing an error message. If you set `opterr' to
zero, the error message is suppressed but we still return '?'.
If a char in OPTSTRING is followed by a colon, that means it wants an arg,
so the following text in the same ARGV-element, or the text of the following
ARGV-element, is returned in `optarg'. Two colons mean an option that
wants an optional arg; if there is text in the current ARGV-element,
it is returned in `optarg', otherwise `optarg' is set to zero.
If OPTSTRING starts with `-' or `+', it requests different methods of
handling the non-option ARGV-elements.
See the comments about RETURN_IN_ORDER and REQUIRE_ORDER, above.
Long-named options begin with `--' instead of `-'.
Their names may be abbreviated as long as the abbreviation is unique
or is an exact match for some defined option. If they have an
argument, it follows the option name in the same ARGV-element, separated
from the option name by a `=', or else the in next ARGV-element.
When `getopt' finds a long-named option, it returns 0 if that option's
`flag' field is nonzero, the value of the option's `val' field
if the `flag' field is zero.
The elements of ARGV aren't really const, because we permute them.
But we pretend they're const in the prototype to be compatible
with other systems.
LONGOPTS is a vector of `struct option' terminated by an
element containing a name which is zero.
LONGIND returns the index in LONGOPT of the long-named option found.
It is only valid when a long-named option has been found by the most
recent call.
If LONG_ONLY is nonzero, '-' as well as '--' can introduce
long-named options. */

/////////// THREAD SAFETY
// Individual stb_vorbis* handles are not thread-safe; you cannot decode from
// them from multiple threads at the same time. However, you can have multiple
// stb_vorbis* handles and decode from them independently in multiple thrads.
/////////// MEMORY ALLOCATION
// normally stb_vorbis uses malloc() to allocate memory at startup,
// and alloca() to allocate temporary memory during a frame on the
// stack. (Memory consumption will depend on the amount of setup
// data in the file and how you set the compile flags for speed
// vs. size. In my test files the maximal-size usage is ~150KB.)
//
// You can modify the wrapper functions in the source (setup_malloc,
// setup_temp_malloc, temp_malloc) to change this behavior, or you
// can use a simpler allocation model: you pass in a buffer from
// which stb_vorbis will allocate _all_ its memory (including the
// temp memory). "open" may fail with a VORBIS_outofmem if you
// do not pass in enough data; there is no way to determine how
// much you do need except to succeed (at which point you can
// query get_info to find the exact amount required. yes I know
// this is lame).
//
// If you pass in a non-NULL buffer of the type below, allocation
// will occur from it as described above. Otherwise just pass NULL
// to use malloc()/alloca()

0.9997 - fix a bug in the read-from-FILE case in 0.9996 addition
0.9996 - query length of vorbis stream in samples/seconds
0.9995 - bugfix to another optimization that only happened in certain files
0.9994 - bugfix to one of the optimizations that caused significant (but inaudible?) errors
0.9993 - performance improvements; runs in 99% to 104% of time of reference implementation
0.9992 - performance improvement of IMDCT; now performs close to reference implementation
0.9991 - performance improvement of IMDCT
0.999 - (should have been 0.9990) performance improvement of IMDCT
0.998 - no-CRT support from Casey Muratori
0.997 - bugfixes for bugs found by Terje Mathisen
0.996 - bugfix: fast-huffman decode initialized incorrectly for sparse codebooks; fixing gives 10% speedup - found by Terje Mathisen
0.995 - bugfix: fix to 'effective' overrun detection - found by Terje Mathisen
0.994 - bugfix: garbage decode on final VQ symbol of a non-multiple - found by Terje Mathisen
0.993 - bugfix: pushdata API required 1 extra byte for empty page (failed to consume final page if empty) - found by Terje Mathisen
0.992 - fixes for MinGW warning
0.991 - turn fast-float-conversion on by default
0.990 - fix push-mode seek recovery if you seek into the headers
0.98b - fix to bad release of 0.98
0.98 - fix push-mode seek recovery; robustify float-to-int and support non-fast mode
0.97 - builds under c++ (typecasting, don't use 'class' keyword)
0.96 - somehow MY 0.95 was right, but the web one was wrong, so here's my 0.95 rereleased as 0.96, fixes a typo in the clamping code
0.95 - clamping code for 16-bit functions
0.94 - not publically released
0.93 - fixed all-zero-floor case (was decoding garbage)
0.92 - fixed a memory leak
0.91 - conditional compiles to omit parts of the API and the infrastructure to support them: STB_VORBIS_NO_PULLDATA_API, STB_VORBIS_NO_PUSHDATA_API, STB_VORBIS_NO_STDIO, STB_VORBIS_NO_INTEGER_CONVERSION
0.90 - first public release
