Please answer the following in C++

#include #include using namespace std; int Is_Palindrome(char str[]); int main() { char input_string[20]; int flag = 0; cout > input_string; flag = Is_Palindrome(input_string); if (flag) { cout

int Is_Palindrome(char str[]){ int i; int flag = 0; int len = strlen(str); for(i=0;i b 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
