Write a program that uses the function isPalindrome given in Example $6-6($Palindrome$).$ Test your program on the following strings:

madam, abba, $22,67876,444244,$ trymeuemyrt

Modify the function isPalindrome of Example $6-6$ so that when determining whether a string is a palindrome, cases are ignored, that is$,$ uppercase and lowercase letters are considered the same.

The isPalindrome function from Example $6-6$ has been included below for your convenience.

bool isPalindrome$($string str$)$

$\{$

int length $=$ str$.$length$()$;

for $($int i $=0$; i $<$ length $/2$; i$++)\{$

if $($str$[$i$]!=$ str$[$length $1$ i$])\{$

return false;

$\}//$ if

$\}//$ for loop

return true;

$\}//$ isPalindrome

Your program should print a message indicating if a string is a palindrome:

madam is a palindrome
