Switch Case

Multiple switch cases can be placed one below the other followed by an expression if all of the switch cases have the same output
Failing to add break; clause will result in Compilation Error

An optional when clause can we used in each cause to define an more complex pattern matching condition

int num = 12;
switch (num % 2)
{
    case 0:
        System.Console.WriteLine("{0} is a even number", num);
        break;
    case 1:
        System.Console.WriteLine("{0} is a odd number", num);
        break;
    default:
        System.Console.WriteLine("Invalid Input was provided");
        break;
}
