Return statement

May 14 2022 5:15 PM

I have a very simple program actually want to grab the concept; for methods with non-void return type as in my case its int, I am obliged to use a return statement but using that return statement am unable to print a number that I have taken from the user. What I need to do? Thanks

I can use the Console.WriteLine() method in this if-else to let the user know that his/her entered number is even or not But this return statement is then for which purpose?

namespace x
{
    class CheckEvenNum
    {
        static int Check(int num)
        {
            if (num % 2 == 0)
            {
                Console.WriteLine("It is a even number");
                return num; // Want to print the number on console with this return
            }
            else
            {
                Console.WriteLine("Not an even number");
                return -1; // Want to print the number on console with this return
            }
        }
        static void Main(string[] args)
        {
            Console.WriteLine("Enter a positive number");
            int number=Convert.ToInt32(Console.ReadLine());    
            CheckEvenNum.Check(number); 
        }
    }
}
