Explanation:
A default constructor is a constructor that present in the class by default with no parameters when we write a new constructor with parameters it is called overloaded constructor.There can be different overloaded constructors in the same class.
The main difference between default constructor and overloaded constructor is that the default constructor does't have any parameters while the overloaded constructors have parameters.

Explanation:
With a little more effort you can make the program allow the user to enter any number of details, but less than 30 overall. We have used here flag, and as a programmer we know why we use the Flag. It is used to check whether certain Boolean condition is fulfilled or not. Here, we are checking whether a given name is present in the array of names, and if it is not present, we add that to the list. And if the name is present, we print, it already exist.

_____Router___ allows the cloud controller to locate instances on separate zones to boost redundancy.
Explanation:
A router, as a networking device, forwards data packets between one computer network and other networks. With a router, one can use wired and wireless devices to connect to the Internet. Unlike a modem, which connects the home network to a wider internet, a router can enable the networks to interact with one another without using the Internet.
