This lab took a little time to figure out but with the help of some classmates figured it out. it took a little time to figure out how to let the program allow the user to only choose the number one. the calculations were easy but the code itself too a little time.This program allows you to chose and input a set of number, then displays the first and last numbers as well as show you how many numbers you entered, then it chooses the two lowest and two highest numbers, after that it adds all the numbers and finds the average of these numbers which is all displayed.
