1. Write a statement to declare screen to be an ostream_iterator initializedto the standard output device that outputs the elements of an int vector object.
2. Consider the following statements:
vector<int> intVector;
Suppose that intVector = {5, 7, 9, 11, 13}. Moreover, suppose that
screen is an ostream_iterator initialized to the standard output deviceto output the elements of an int vector object. What is the effect of thefollowing statement?
copy(vecList.begin(), vecList.end(), screen);
