Write a function that determines whether a string is a palindrome. ?? Same lette

Question

Write a function that determines whether a string is a palindrome. ?? Same letters backward as forward. ?? Ignore characters that are not letters.
Use pointers to compare characters. ?? One pointer works from beginning toward end. ?? One pointer works from end toward beginning. ?? Each skips over characters that are not letters. ?? If characters in corresponding positions do not match, return 0 (false). ?? If the pointers meet, return 1 (true).
?? You will need ?? isalpha() ?? tolower() or toupper()




#include <stdio.h>
int main(void) { char input[1000] = ""; printf ("Enter a message:");
fgets(input, 1000, stdin);
input[999] = 0;
if (is_palindrome(input))    {    printf("Palindrome ");    } else    {    printf ("Not apalindrome ");    }
return 0; }
can someone show me and let me know how to write this programwithout changing much of what i got and and the same format ?

Explanation / Answer

please rate - thanks #include #include #include // This function determines if a string is a palindrome. int is_palindrome(char* message) {     char *p,*q;     p=q=message;     while(*q!='')             q++; // q represents the null character.     q-=2;//q represents the last character ofstring.     while(!isalpha(*p))            p++; while(!isalpha(*q))            q--; while(tolower(*p)==tolower(*q)&&p
