Question

C# Programming:

A.   Create a console-based application named TippingTable.cs that lets restaurant patrons approximate the correct tip for meals. Prices range from $10 to $100, and tipping percentage rates range from 10% to 25%. The program uses several loops. The program prompts restaurant patrons for user input:

Lowest tipping percentage

Highest tipping percentage

Lowest possible restaurant bill

Highest possible restaurant bill

B.     Write a GUI program named TippingTableGUI that creates a tipping table after the user clicks a button. Get the lowest and highest tipping percentages and the lowest and highest possible restaurant bills from TextBox entries.

namespace restaurant
{
class Program
{
static void Main(string[] args)
{
int i,tp,b,ltp, htp, lb, hb;
tp = 0;
for (i = 1; i < 5; i++)
{
Console.WriteLine("Lowest tipping percentage");
ltp = Convert.ToInt32(Console.ReadLine());
Console.WriteLine("Highest tipping percentage");
htp = Convert.ToInt32(Console.ReadLine());
Console.WriteLine("Lowest possible restaurant bill");
lb = Convert.ToInt32(Console.ReadLine());
Console.WriteLine("Highest possible restaurant bill");
hb = Convert.ToInt32(Console.ReadLine());

Console.WriteLine("Enter Bill amount");
b = Convert.ToInt32(Console.ReadLine());

if (b >= lb && b <= (hb / 2))
tp = b * ltp / 100;

else if (b > hb / 2 && b <= hb)
tp = b * htp / 100;

Console.WriteLine("Tip amount is " + tp);
Console.ReadKey();
}
}
}
}

DataGridViewRow row = (DataGridViewRow)dataGridView1.Rows[0].Clone();
row.Cells[0].Value = b;
