b) In the following block of code, list all containers, iterators, algorithms, and functors. 10 If one of them is not in the code, state that. What does the code do? vector a{1,3},b{4,5},c swap (a,b); copy (a.begin( ), a.end( ), back_inserter(b)); c) When dealing with vectors, explain the difference between the functions size() 6 and capacity()
