Using the computational language C++ it is possible to write a code is possible to create a function that stores items like this:

<h3>Writting the code in C++: </h3>

//Header files

#include <iostream>

#include <string>

#include <fstream>

using namespace std;

//Class inventoryItem

class inventoryItem

{

public:

//Variable declaration

string itemName;

string itemNumber;

double itemPrice;

int itemQuantity;

};

//implementation of menuItems() function.

void menuItems()

{

// Display the Menu

cout << "=============================\n";

cout << " 1) Add an item to memory\n"

<< " 2) Search memory for an item \n"

<< " 3) List what's in memory\n"

<< " 4) Total value on hand\n"

<< " 5) Save to a file\n"

<< " 6) Read from a file\n"

<< " 0) Exit Program" << endl;

}

//main method.

int main()

Routing between autonomous systems is referred to as ______ .

Gennadij [26K]

Answer:

The correct answer for the given question is an option(b) i.e "interdomain routing".

Explanation:

The Interdomain Routing algorithm protocol works between the domains. The protocol which is used in the interdomain routing is called as exterior gateway protocol. In the interdomain routing protocols works between the autonomous systems, it means they are taking place in the autonomous networks.

Intradomain routing works within the domain. They are not works between the autonomous systems so the option(a) is incorrect.
Out-of-domain are neither work in within or between the system so option(d) is incorrect.
