Find Palindrome in C

Palindrome is a sequence of characters which reads same backward or forward.

sample code for finding palindrome string

int is_palindrome_string(const char string[]){
        int left = 0, right = 0;
        int result = 1;
        right = strlen(string)-1;
        for(;left < right; left++, right--){
                if(string[left] != string[right]){
                        result = 0;
                        break;
                }
        }

        return result;
}

sample code for finding palindrome number. Using above logic

int is_palindrome_number(unsigned int number){
        char buffer[256]={0x00};
        char pale_buffer[256]={0x00};
        int len =0;
        len = snprintf(buffer, sizeof(buffer)-1, "%d", number);
        return is_palindrome_string(buffer);
}
