Check if the given is right or wrong (Tor F) 1) So in a functional programming languages, the build in operator +, * etc behave as pure functions and can be used anywhere that a function of any other name can be used. 2) In Oo languages the classes can be used to implement “type obstraction”, in functional languages the high order functions can be used to implement ” control obstraction”. 3) In language that implement “tail-recursion”. It is generally best to avoid recursion altogether for better performance and to avoid potential tack overflows. 4) “Iterators provide a semantic mechanism for stepping through a sequence of value in a manner that can be free from the influence of external side-effect, such as those that could occur in multithreaded applications.
