Question
Design an Inventory class that can hold information for an item in a retail store%u2019s inventory.
The class should have the following private member variables:
Variable Name Description
itemNumber An int that holds the item%u2019s number.
quantity An int that holds the quantity of the item on hand.
cost A double that holds the wholesale per-unit cost of the item
The class should have the following public member functions:
Member Function Description
default constructor Sets all the member variables to 0.
constructor #2 Accepts an item%u2019s number, quantity, and cost as arguments. Calls other class functions to copy these values into the appropriate member variables. Then calls the setTotalCost function.
setItemNumber Accepts an int argument and copies it into the itemNumber member variable.
setQuantity Accepts an int argument and copies it into the quantity member variable.
setCost Accepts a double argument and copies it into the cost member variable.
getItemNumber Returns the value in itemNumber.
getQuantity Returns the value in quantity.
getCost Returns the value in cost.
getTotalCost Computes and returns the totalCost.
Demonstrate the class by writing a simple program that uses it. This program should validate the user inputs to ensure that negative values are not accepted for item number, quantity, or cost.
Explanation / Answer
#include<iostream>
using namespace std;
class Inventory
{
public:
int itemNumber,Quantity;
double Cost,total;
Inventory()
{
itemNumber=0;
Quantity=0;
Cost=0;
}
Inventory(int number,int quantity,double cost)
{
setItemNumber(number);
setQuantity(Quantity);
setCost(Cost);
}
void setItemNumber(int number)
{
itemNumber=number;
}
void setQuantity(int quantity)
{
Quantity=quantity;
}
void setCost(double cost)
{
Cost=cost;
}
int getItemNumber()
{
return itemNumber;
}
int getQuantity()
{
return Quantity;
}
double getCost()
{
return Cost;
}
double getTotal()
{
total=(double)Cost*Quantity;
return total;
}
};
