- Create a do while loop, when user enter "0", stop the loop.
- User enter item name, price, quantity, save these info and subtotal to array.
- increase "count++"

-conver price(decimal, Convert.ToDecimal() ) and quantity(int) to do mulplication for subtotal

Answer 1

Here is code:

using System;

namespace ConsoleApp // Project name
{
class Program
{
static void Main(string[] args)
{
string s;
string[,] items = new string[100, 4];
double total = 0;
int i = 0;
// read input
while (true)
{
Console.Write("Enter item name (enter 0 to quit): ");
s = Console.ReadLine();
if (s == "0")
{
break;
}
items[i, 0] = s;
Console.Write("Enter price : ");
s = Console.ReadLine();
items[i, 1] = s;
Console.Write("Enter quantity : ");
s = Console.ReadLine();
items[i, 2] = s;
double cost = Convert.ToDouble(items[i, 1]) * Convert.ToInt16(items[i, 2]);
total += cost;
items[i, 3] = cost.ToString();
i++;
}
for (int j = 0; j < i; j++)
{
Console.WriteLine("Item name : " + items[j, 0]);
Console.WriteLine("Price: " + items[j, 1]);
Console.WriteLine("Quantity : " + items[j, 2]);
Console.WriteLine("Sub Total : " + items[j, 3]);
}
Console.WriteLine("Total : " + total);
Console.ReadKey();
}
}
}

Output:
