Object:-Write a Program in java to find out the factorial of the number
import java.util.Scanner; class Factorial { public static void main(String...s) { int n,fac=1,i; Scanner sc = new Scanner(System.in); System.out.println("Enter a number: "); n = sc.nextInt(); for(i=1;i<=n;i++) fac*=i; System.out.println("nFactorial = "+fac); sc.close(); } }
Enter a number: 5 Factorial=120
We can find factorial of any number by multiplying it with all the numbers below it.
For example, factorial of 5 is 5*4*3*2*1 = 120
