hi,
I am a begineer to c sharp. I have written a code for
finding out prime numbers. Can anyone identify what are the
flaws in my code.
Kindly donot complex the code or present logic because i am
new to c sharp and just started learning programming
language.Thanks in advance.

class Program
{
static void Main(string[] args)
{
int a,b=1;
a = int.Parse(Console.ReadLine());
c= int.Parse(Console.ReadLine());
if (a % b == 0 && a % 2 != 0 && a % a == 0)

Console.WriteLine(a);
else if (a % b == 0 && a % 2 == 0)
Console.WriteLine(a%2);
Console.WriteLine("Number is not
PRIME");
Console.ReadLine();

}
}
}
