int a, b, c;
switch(ch)
{
case 1:
Console.Write("Enter A:");
a = Convert.ToInt32(Console.ReadLine());
Console.Write("Enter B:");
b = Convert.ToInt32(Console.ReadLine());
c = a + b;
Console.WriteLine("Sum = {0}", c);
break;
case 2:
Console.Write("Enter A:");
a = Convert.ToInt32(Console.ReadLine());
Console.Write("Enter B:");
b = Convert.ToInt32(Console.ReadLine());
c = a - b;
Console.WriteLine("Difference = {0}", c);
break;
case 3:
Console.Write("Enter A:");
a = Convert.ToInt32(Console.ReadLine());
Console.Write("Enter B:");
b = Convert.ToInt32(Console.ReadLine());
c = a * b;
Console.WriteLine("Product = {0}", c);
break;
case 4:
Console.Write("Enter A:");
a = Convert.ToInt32(Console.ReadLine());
Console.Write("Enter B:");
b = Convert.ToInt32(Console.ReadLine());
c = a / b;
Console.WriteLine("Quotient = {0}", c);
break;
