Please answer in C++

Given a sorted list of integers, output the middle integer. Assume the number of integers is always odd.

Ex: If the input is:

2 3 4 8 11 -1
(a negative indicates the end), the output is:

4
The maximum number of inputs for any test case should not exceed 9. If exceeded, output "Too many inputs".

Hint: First read the data into a vector. Then, based on the number of items, find the middle item.

1. you have a small business that is divided into 3 departments: accounting, sales, and administration. these departments have the following number of devices (computers, printers, etc.): accounting-31, sales-28, and administration-13. using a class c private network, subnet the network so that each department will have their own subnet. you must show/explain how you arrived at your conclusion and also show the following: all available device addresses for each department, the broadcast address for each department, and the network address for each department. also, determine how many "wasted" (not usable) addresses resulted from your subnetting (enumerate them).
