[Muzamil]

Can you guys tell me what I'm making mistake I want to display output as
Enter the number : 4
Factorial of 4 is : 1 x 2 x 3 x 4 = 24!


using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace Factorial
{
class fact
{
public int[] factorial(int num)
{
int[] fact = new int[10];
for (int i = 0; i < num; i++)
{
fact[i] = fact[i] + i;
}
return fact;
}
}

class fact
{
static void Main(string[] args)
{
fact num1 = new fact();
int num;
int[] result;

num = Convert.ToInt32(Console.ReadLine());

result = num1.factorial(num);
for (int i = 0; i < num; i++)
{

Console.Write(result[i]);

Console.WriteLine();
Console.WriteLine();
}

}
}
}
