Question

Using C#: In Chapter 4, you created an interactive application named GreenvilleRevenue that prompts the user for the number of contestants entered in this year's and last year's Greenville Idol competition if each contestant pays a $25 entrance fee. The program also displays one of three appropriate statements specified in the case problem in Chapter 4, based on a comparison between the number of contestants this year and last year. Now, modify the program so that the user must enter a number between 0 and 30 inclusive for the number of contestants each year. If the user enters an incorrect number, the program prompts for a valid value. Below is the code from Chapter 4;

namespace GreenvileRevenue
{
    class Program
    {
        static void Main(string[] args)
        {
            int entFee = 25;
            Console.WriteLine("Enter the number of contestants entered in last year's competition: ");
            int contLast = Convert.ToInt32(Console.ReadLine());
            Console.WriteLine(" Enter the number of contestants entered in this year's competition: ");
            int contCurr = Convert.ToInt32(Console.ReadLine());
            Console.WriteLine(" The revenue expected for this year's competition is {0:C}", contCurr * entFee + ' ');
            if (contCurr > contLast * 2)
            {
                Console.WriteLine(" The competition is more than twice as big this year! ");
            }
            else

            if (contCurr > contLast && contCurr <= (contLast * 2))
            {
                Console.WriteLine(" The competition is bigger than ever! ");
            }
            else

            if (contCurr < contLast)
            {
                Console.WriteLine(" A tighter race this year! Come out and cast your vote! ");
            }
        }
    }
}
