Question

C++

1. Create a class named Inventoryltem. 2. In this class you should have two class member variables o id of type integer o price of type float 3. Provide a default constructor that initializes both of these values to 0. 4. Write a parameterized constructor to initialize these values to id and price parameters passed-in to the constructor. This constructor allows us to set the id and price class member variables to the values entered by the user. 5. Write getters for both id and price so we can retrieve these values when displaying the Inventorvitems to the user. 6. Remove any use of the parallel arrays and create a single array of type Inventoryltem 7. Continue to ask the user for the id and price values for each inventory item. 8. Continue to validate the input provided by the user using a loop. 9. From the valid values provided by the user, construct an Inventoryltem and store it in the new array. 10. You can augment the loops and functions we've created so far to work with the single Inventoryltem array.

#include <iostream>

using namespace std;

bool checkinventoryid(int id)

{

   return id > 0;

}

bool checkinventoryprice(float price)

{

   return price > 0;

}

void endProgram()

{

   system("pause");

   exit(0);

}

void errorID(string str)

{

   cout << "Invalid Id!!! " << str << " should be greater than 0" << endl;

}

void errorPrice(string str)

{

   cout << "Invalid Price!!!" << str << " should be greater than 0" << endl;

}

int inputId()

{

   int inventoryitem = 0;

   cout << "Enter the Inventory id: ";

   cin >> inventoryitem;

   while (!checkinventoryid(inventoryitem))

   {

       errorID("Inventory id");

       cout << "Enter the Inventory id: ";

       cin >> inventoryitem;

   }

   return inventoryitem;

}

float inputPrice()

{

   float price = 0.0;

   cout << "Enter the Inventory price: ";

   cin >> price;

   while (!checkinventoryprice(price))

   {

       errorPrice("Inventory price");

       cout << "Enter the Inventory price: ";

       cin >> price;

   }

   return price;

}

void display(int id, float price)

{

   cout << "------------\n";

   cout << "ID: " << id << endl;

   cout << "Price: " << price << endl;

}

int main()

{

   for (int i = 0; i < 5; i++)

   {

       int inventoryitem = inputId();

       float price = inputPrice();

       display(inventoryitem, price);

   }

}
