A program to find whether a given number is prime or not using c#
using System;
class Program
{
static void Main(string[]args)
{
int i;
Console.WriteLine("enter any number");
int a = int.Parse(Console.ReadLine());
for(i=2;i<a;i++)
{
if(a%i==0)
break;
}
if(a==1||i==a)
Console.WriteLine("the number is prime");
else
Console.WriteLine("the number is not pirme");
Console.Read();
}
}

A program to find factorial of a number using functions in c#
class Program
{
static int Factorial(int n)
{
if (n <= 1)
return 1;
int fact = 1;
for (int i = 2; i <= n; i++)
{
fact = fact * i;
}
return fact;
}
static void Main(string[] args)
{
Console.Write("Enter a Number to find factorial: ");
int n = Convert.ToInt32(Console.ReadLine());
int r = Factorial(n);
Console.WriteLine(n.ToString() + "! = " + r.ToString());
Console.ReadLine();
}
}
}
