a program that uses the function isPalindrome. 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 The user must be prompted a string, and the string must be stored in testingstring and then compared in the if statement. example: Enter string : MaDam, 22, aBba, 67876, 444244, trYmeueMyrt MaDAm is a palindrome. 22 is a palindrome. aBba is a palindrome. 67876 is a palindrome. 444244 is not a palindrome. trYmeueMyrt is a palindrome. Note : Please check 'isPalindrome' with the required string arguments and if the program produces the correct output that inputed
