- Java Assignment: Experiment with naming rules in Java Does the language use static or dynamic scoping? Can scopes nest? Are they open or closed? Does the scope of a name encompass the entire block in which it is declared, or only the portion after the declaration? How does one declare mutually recursive types or subroutines? Can subroutines be passed as parameters, returned from functions, or stored in variables? If so, when are referencing environments bound?

- Describe how polymorphism enables you to program "in the general" rather than "in the specific"? Give some examples, not the ones used in the book (C++ How to Program by Paul J. Deitel, Harvey Deitel Tenth Edition).Correct this in C <declares> -> <keyword> <ident> ; | <keyword> <ident> ; <declares>Question Write a c++ program that determines whether or not a string of alphanumeric characters is a palindrome. Ignore any whitespace characters or punctuation when processing the string. You will be required to demonstrate pointer math and dereferencing. The algorithm determines whether a string or palindrome will have this header: bool isPalindrome(const char* input, int size). You will be required to separate your interface from your implementation; you must have a header file (.h) for your interface, and a source file (.cpp) for your implementation. Be sure to perform data validation on your input to prevent buffer overflows. Your code should present the user with prompts similar to the following: (image included) Here are some example palindromes you can test with: Mr. Owl ate my metal wormDo geese see God?Was it a car or a cat I saw?Murder for a jar of red rumA nut for a jar of tunaGo hang a salami, I'm a lasagna hog!
