i try, but the input prompt the user enter 6 times names,but i just put 3 people.
it suppose to be when the user put 3 people, the program will prompt the user to enter 3 names only.then the program must arrange the name alphabetically.

do you want to sort it by first name or last name ?

nope...just sort it by the first alphabet...

example like:
John
Gary
Ben

the sorder will be:
first:Ben
last:John
