We studied the rand() and srand(int) library functions. The function rand() returns pseudorandom numbers. What does pseudorandom mean? What is srand for?
a) Repeated calls to the rand() function returns a string of numbers that are mostly different but they aren’t random in any sense. b) Pseudorandom numbers are things that resemble numbers but aren’t numbers. c) In scientific use the word pseudo means resembling. A pseudorandom number sequence resemble random number sequence, but are not strictly random. d) The function srand(arg) is a helper function for rand(). It must be called with the same argument, just before rand(), every time rand() is called. e) The function srand(arg) is the seeding function for rand(). Each call to s srand(arg) with a different argument enables a sequence of calls to rand() to generate a different sequence of pseudorandom numbers.
Which of the following statements is false?
a. Stream method sort orders a stream’s elements into ascending order by default. b. To create a collection containing a stream pipeline’s results, you can use Stream method collect (a terminal operation). As the stream pipeline is processed, method collect performs a mutable reduction operation that places the results into an object, such as a List, Map or Set. c. Method collect with one argument receives an object that implements interface Collector (package java.util.stream), which specifies how to perform a mutable reduction. d. Class Collectors (package java.util.stream) provides static methods that return predefined Collector implementations.
