Question

This assignment requires that you modify the given program. The program uses a do-while repetition statement and if-else if selection statement to accomplish its task. You are required to modify it by replacing the do-while with a for repetition statement, and also replace the if-else if with a switch selection statement. Your modified program must function in the same way as the original program.

Modifications should only be made to code that is in the Main method.

Explanation / Answer

Here is the modified code for you:

using System;

public class Basket
{
private int breadCount;
private int milkCount;
private int cheeseCount;

public int getBreadCount()
{
return breadCount;
}

public void setBreadCount(int r)
{
breadCount = r;
}

public int getMilkCount()
{
return milkCount;
}

public void setMilkCount(int r)
{
milkCount = r;
}

public int getCheeseCount()
{
return cheeseCount;
}

public void setCheeseCount(int r)
{
cheeseCount = r;
}

public void displayBill()
{
double breadCost = getBreadCount() * 12.95;
double milkCost = getMilkCount() * 6.95;
double cheeseCost = getCheeseCount() * 24.95;

double subTotal = breadCost + milkCost + cheeseCost;
double tax = subTotal * 6 / 100;

Console.WriteLine(" ");
Console.WriteLine(" ACME SUPER STORE");
Console.WriteLine(" ==================== ");
Console.WriteLine(" Customer Receipt ");
Console.WriteLine(" Expensive Bread {0:C} ", breadCost);
Console.WriteLine(" Expensive Milk {0:C} ", milkCost);
Console.WriteLine(" Expensive Cheese {0:C} ", cheeseCost);
Console.WriteLine(" Subtotal {0:C} ", subTotal);
Console.WriteLine(" Sales Tax (6%) {0:C} ", tax);
Console.WriteLine(" Total {0:C} ", subTotal + tax);
}

public void displayWelcome()
{
Console.WriteLine(" ACME SUPER STORE");
Console.WriteLine(" ==================== ");
Console.WriteLine(" 10 Items Or Less Isle ");
Console.WriteLine(" We are strict about that...! ");
}
}

public class TestBasket
{
public static void Main(string[] args)
{
Basket myBasket = new Basket();
int input = 0;
int MAX_PRODUCTS = 10;
//int productCount = 0;

myBasket.displayWelcome(); //display welcome message

//do
for(int productCount = 0; productCount < MAX_PRODUCTS;)
{
Console.Write(" Product No. {0} ", productCount + 1);
Console.Write("Enter product code 1, 2, 3 or -1 to quit: ");
input = Convert.ToInt32(Console.ReadLine());
           switch(input)
           {
//if (input == 1)
case 1:

//}
break;
//else if (input == -1) //user decides to quit
case -1:
//{
productCount = MAX_PRODUCTS + 1; //increase number of products so that loop terminates
Console.WriteLine("displaying total...");
//}
break;
//else
default:
Console.WriteLine("Invalid product number");
}

} //while (productCount < MAX_PRODUCTS); //loop while number of products is less than max

myBasket.displayBill(); //display bill

Console.ReadKey();
}
}
