Write a program that uses the function isPalindrome given below. Test your program on the following strings: madam, abba, 22, 67876, 444244, trymeuemyrt. Modify the function isPalindrome given so that when determining whether a string is a palindrome, cases are ignored, that is, uppercase and lowercase letters are considered the same. 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;
}

return true;
}

Answer:

#include <iostream>

#include <string>

using namespace std;

bool isPalindrome(string str)

{

   int length = str.length();

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

   {

       if (tolower(str[i]) != tolower(str[length - 1 - i]))

           return false;

   }

   return true;

}

int main()

{

   string s[6] = {"madam", "abba", "22", "67876", "444244", "trymeuemyrt"};

   int i;

   for(i=0; i<6; i++)

   {

       //Testing function

       if(isPalindrome(s[i]))

       {

           cout << "\n " << s[i] << " is a palindrome... \n";

       }

       else

       {

           cout << "\n " << s[i] << " is not a palindrome... \n";

       }

   }    

       

   return 0;

}
