A router is a web device that directs packages over a web towards their final destination is true.
<h3>What is the router?</h3>
- A router is a machine that combines two or more packet-switched grids or subnetworks.
- A router accepts and data transmits on computer networks. Routers are sometimes confused with network hubs, modems, or network controllers.
- However, routers can integrate the functions of these components, and secure with these devices, to improve Internet entry or help create interaction networks.
- A router is a device that is used for forwarding the internet connection to all the related devices.
- A Wi-Fi connects the networking parts of a router and a wireless access point.
- A wireless router (or Wi-Fi router) works much like a wired router, but it returns wires with wireless radio calls.

Answer:
#include <iostream>
#include <map>
using namespace std;
int main()
{
map<int, int> numbers;
cout << "Enter numbers, 0 to finish" << endl;
int number;
while (true) {
cin >> number;
if (number == 0) break;
numbers[number]++;
}
for (pair<int, int> element : numbers) {
std::cout << element.first << ": occurs " << element.second << " times" << std::endl;
}
}
Explanation:
One trick used here is not to keep track of the numbers themselves (since that is not a requirement), but start counting their occurrances right away. An STL map< > is a more suitable construct than a vector< >.
A benefit, profit, or value of something that must be given up to acquire or achieve something else. Since every resource (land, money, time, etc.) can be put to alternative uses, every action, choice, or decision has an associated opportunity cost<span>.</span>
