Write a program to input an integer and find its factorial.

Write a program to input an integer and find its factorial. Factorial of a number is the product of all natural numbers till that number. For example factorial of 5 is 120 since 1×2×3×4×5=120.

class Factorial
{
	public static void main(Strign arr[])
	{
		Scanner sc=new Scanner(System.in);
		int i,f=1,n;
		System.out.println("Enter a number:");
		n=sc.nextInt();
		for(i=1;i<=n;i++)
		{
		f=f*i;
		}
		System.out.println("Factorial="+f);
	}
}
