Answer the following statements true (T) or false (F)

Question

1) Use the set_union algorithm to create a set of all the elements that are in either or both
of two sorted sets (both sets of values must be in ascending order).
2) Because Standard Library algorithms process containers directly, one algorithm can often
be used with many different containers.
3) Use the for_each algorithm to apply a general function to every element in a range;
for_each does not modify the sequence.
4) By default, the sort algorithm arranges the elements in a range in ascending order.
5) Use the merge algorithm to form a new sequence by placing the second sequence after
the first.

Answer 1

1. True.
2. False. Because Standard Library algorithms process containers only indirectly through
iterators, one algorithm can often be used with many different containers.
3. False. It is possible to modify the sequence if the general function receives the elements
by reference.
4. True.
5. False. The merge algorithm combine two sorted ascending sequences of values into a
third sorted ascending sequence.
