Answer 4

but...for example, I write a code that ask a user to enter a word. the purpose is to check whether the word is palindrome or not. but at the same time, I want compiler to automatically count the length of the word( as the array size) . how could I do that? should I use the "str.string();" ? but I still confused on how to use it. :(
