Design a c++ program that asks the user for a series of names (in no particular order). After the final person's name has been entered, the program should display the name that is first alphabetically and the name that is last alphabetically. For example, if the user enters the names Kristen, Joel, Adam, Beth, Zeb, and Chris, the program would display Adam and Zeb. Must use at least one function in addition of main() and loop .
