C# Program which calculated factorial to prime function

C# Program which calculated factorial to prime function

Program Statement:

Write two functions max(int,int) and prime(int). max function will take two arguments and will return the maximum of two numbers in main. Then main function will pass this calculated factorial to prime function which will show that passed value is prime or not.

Solution:

 public class _max
    {
        public int max(int a, int b)
        {
            if (a > b)
                return a;
            else
                return b;
        }
        public void prime(int n)
        {
            if (n == 1)
                Console.WriteLine("\n\t\t{0} is maximum but not prime number!\n\n", n);
            if (n >= 2)
            {
                if (n % 2 != 0)
                {
                    Console.WriteLine("\n\t\t{0} is maximum and Prime number!\n\n", n);
                }
                else
                { Console.WriteLine("\n\t\t{0} is maximum but not a Prime number!\n\n", n); }
            }
        }
    }
