Question

15. What is an Associative Array? a. A type whose variables may store different data type values at different times. b. A data type in Python that can store different data types and is immutable c. A homogeneous aggregate of data elements in which an individual element is identified by its position in the aggregate. d. An unordered collection of data elements that are indexed by an equal number of values called keys. 16. General semantics of calls to a subprogram include? a. Parameter passing methods b. Save the execution status of calling program c. Transfer of control and arrange for the return d. All of the above 17. A base class contains all data and methods which are common to all objects in its inheritance hierarchy. a. TRUE b. FALSE 18. Which kind of variable generally has the longest lifetime? a. A heap-dynamic variable b. A stack-dynamic variable c. Both always have exactly the same lifetime d. Neither has any lifetime. 19. A variable in Prolog must start with an upper-case V (or an underscore) a. TRUE b. FALSE
