Question

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.

Answer 1

Solution:

1. Ture

Reason:

In functional programming language, we use + and / operator anywhere in the program and they behave as a pure function in the whole program.

2. Ture

Reason: In OO programming languages the classes are used to express the concept of data abstraction i.e. hiding non-essential details form outside world while in functional programming languages, high level functions implement control obstructions.

3. False

Reason: The overflow in the recursion mainly occur when the terminating condition is missing or not specified with correct constraints.

4. True

Reason: The iterators is a concept which is used to iterate over a sequence of data or values and helps in creating multithreaded applications.
