namespace PrimeNumber
{
class Program
{
static void Main(string[] args)
{
Check_Prime();
Check_Prime();
Console.Read();
}
private static int Check_Prime()
{
Console.WriteLine("Enter a number");
int number = Convert.ToInt32(Console.ReadLine());
int i;
for (i = 2; i <= number - 1; i++)
{
if (number % i == 0)
{
Console.WriteLine("{0} is not a prime number", number);
}
}
if (i == number)
{
Console.WriteLine("{0} is a prime number", number);
}
return 0;
}
}
