Palindromes
A palindrome is a string that is identical to itself when reversed. For example, "madam", "dad",
and "abba" are palindromes. Note: the empty string is a palindrome, as is every string of length
one.
Write some code in the main () function to accomplish the following tasks:
Having written code to extract data from the keyboard (stdin) in Lab 3, reuse that code
to prompt the user to enter a string between 0 and 255 characters in length. You should
ignore whitespace and punctuation, and all comparisons should be case-insensitive.
Process the entries from the keyboard and store them in the queue ADT provided in the
lab 5 code package.
Use the is_palindrome () function ADT provided to implement a simple palindrome
verification of the data entered. Here is the signature and documentation for the function:
bool is palindrome (char *text)
Return true if text is a palindrome, false otherwise.
Turn in your commented program and a screen shot (script) of the execution run of the
program. Include some sample tests in your captured code run. Examples of valid palindromes:
"a"
"aa"
"aaa"
"aba"
"abba"
"Тасо сat"
"Madam, I'm Adam"
"A man, a plan, a canal: Panama"
"Doc, note: I dissent. A fast never prevents a fatness. I diet on cod."

Code specific to carrying out this lab exercise
lab5.h
Header definitions for functions specific to carrying out this lab exercise

A makefile that creates the "queue" executable easier (including clean)
Here is a quick reference to the functions provided in dynarray.c:
typedef dynarray_t;
// dynamic array struct
/* Basic/common operations */
// initialize struct
// free struct
void
dynarray_init
dynarray_free
size_t dynarray_size
(dynarray_t *a);
(dynarray_t *a);
(dynarray_t *a);
size_t dynarray_is_empty(dynarray_t *a);
void
// return element count
// return true if empty
/* Stack operations * /
1
// add to back
// remove from back
// return back
void
dynarray_push (dynarray_t *a, data_t item);
data_t dynarray_pop (dynarray_t *a);
data_t dynarray_top (dynarray_t *a);
/* Queue operations * /
// add to back
// remove from front
// return front
void
dynarray_enqueue (dynarray_t *a, data_t item);
data_t dynarray_dequeue (dynarray_t *a);
data_t dynarray_front
(dynarray_t *a);
In addition, you may find the following functions from ctype.h useful in this lab:
int tolower (int c)
Converts c to its lowercase equivalent. If no conversion is possible, the value returned is
unchanged. NOTE: For the purposes of this lab, you may use this function as if it accepts and
returns a char.
int isdigit (int c)
Returns non-zero integer (true) if c is a decimal digit (0-9); otherwise it returns zero (false).
