StockItem

This class represents an item that is part of an inventory. The item has an item name, a cost and a profit margin (which can be positive or negative). By using the profit margin, it can derive the price of the item. This example illustrates rounding.

Problem Statement

Write the code for the StockItem class. The solution must meet the following requirements:

• Should get and set the name, cost and profit margin of the stock item
• Should calculate the price of the item, to the nearest cent, using the profit margin as a percent (a profit margin of 45 means 45%)
• Use the rounding where values under a half-cent are rounded down and values greater than or equal to a half-cent are rounded up

Use the following class diagram when creating your solution.

using System;
namespace Topic.E.Examples
{
    public class StockItem
    {
        public double Cost { get; set; }

        public double ProfitMargin { get; set; }

        public StockItem(string itemName, double cost, double profitMargin)
        {
            this.ItemName = itemName;
            this.Cost = cost;
            this.ProfitMargin = profitMargin;
        }

        public string ItemName { get; set; }

        public double Price
        {
            get
            {
                // Round to the nearest cent
                double price = Cost;
                price += Cost * (ProfitMargin / 100);
                return Math.Round(price * 100) / 100.0;
            }
        }
    }
}
