![Write a program to check whether a given word is a palindrome by using pointers
A palindrome is a word that is the same when spelled from the front and from the back.
For example, Kayak, Level, Racecar, Radar, Rotator
- Create 2 char arrays and 2 corresponding pointers to the arrays
- Initialize array to the word
- Copy array1 backwards to array2
Compare array1 and array2, if they are the same, the word is a palindrome
Modify the pseudocode below to produce the sample output.
char word[5]= "kayak";
char reverseWord[5];
char *f = word;
char *b = reverseWord;
for ()
*(b_from_start) = *(f_from_end);
Copy word to reverseWord but starting from the back
for()
{
Compare word and reverseWord
if same
palindrome;
Sample:
word_reverse
